EPITHELIAL TISSUE
epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers.
HERMAPHRODITE
a hermaphrodite is having both male and female sexual characteristics and organs; at birth an unambiguous assignment of male or female cannot be made
EUKARYOTES
an organism with cells characteristic of all life forms except primitive microorganisms such as bacteria (mammals)

Carbohydrrate-Fibrous
*Robin M.
Carbohydrate Fibrous: Complex carbohydrates that come from green vegetables.
-Image of green veggies.
K-STRATEGISTS
k strategists are the opposite of r strategist. they are large body low fecundity, low mortality, longer life and with populations approaching the carrying capacity of the environment, controlled by density-dependent factors.
Stigma & Style of Carpel
*Robin M.
Stigma & Style of Carpel: Simple pistil or one element of a compound pistil.
-My image is one of a female flower that represents the stigma and style of a carpel.
R-STRATEGIST
lizards are an example of r-strategist because they produce many offspring, are weak competitors in crowded niches, and are usually of small body size.
Parenchyma Cell
*Robin M.
Parenchyma Cell: The most common type of plant cell. It stores starch, oils, and water for the plant. You can find parenchyma cells throughout a plant. These cells have thin walls and large water-filled vacuoles in the middle.
-My image is one of a flower that represents a plant.
PROTEIN-FIBROUS
an example of fibrous proteins would be keratins and keratins can be found in the hair.
Deciduous Leaf
*Robin M.
Deciduous Leaf: A deciduous leaf is a leaf from a plant having foliage that sheds annually at the end of the growing season.
-My image is one of a leaf, this leaf is one of many that transforms in the season of summer going into fall.
LONG DAY PLANTS
A plant which requires light for a longer period than it would normally receive from daylight in order to induce flowering
Cellulose
*Robin M.
Cellulose: Cellulose is an organic compound with the formula (C6H1005) a polysaccharide consisting of a linear chain of several hundred over to ten thousand linked glucose units.
-My image is one of me in my polo shirt. I used this image because my shirt is made of cotton, and cellulose has an important part in making cotton.
Meristem
*Robin M.
Meristem: The tissue in all plants consisting undifferentiated cells and found in zones of the plant where growth can take place.
-My photo is one of a meristem.
Enzymes
*Robin M.
Enzymes: Proteins that catalyze (increase the rate of) chemical reactions.
-This image represents the enzymes that were used involving movements and muscle. I chose this picture because you can see the stress my little cousin put on his face while gripping my arm, through his muscles and veins in his neck.
PARASITE
a parasite is an organism that benifits off another organism and but the host doesn't benefit at all and is being harmed. (picture of my neighbor's dog from a distance)
ANNELID
Xerophyte
A Xerophyte is a plant that is able to survive in an environment in which water is little or nonexistent such as a dessert. Thus this cactus is a prime example of a xerophyte.
Niche
A niche is any species that uses abiotic and biotic resources in the environment. This is a picture of DeMeece, all humans are niches.
Enzymes
Enzymes are essential to any biological process due to the fact that most biological reactions require enzymes to lower the needed activation energy allowing for quicker reaction time. For instance enzymes are what allow my dogs' cells to undergo cellular respiration and thus breathe.
Prokaryote
Prokaryotes are organisms that cells lack a membrane-enclosed nucleus nad membrane-enclosed organelles. Eggs are prokaryotic.
19. K - Strategist
K- Strategist - a human being is an example of an K- Strategist. Species of organism that uses a survival and reproductive strategy characterized by low- fecundity, longer life and with populations approaching the carrying capacity of the environment
Vascular Plant Tissue
Vascular plant tissue is complex tissue found in plants. It consists
of mainly the xylem and phloem which transport fluid and nutrients. In the picture not only the does the tree have vascular plant tissue but so does the leaves.
Animal that has segmented body
An animal that has a segmented body part has an exoskeleton and jointed appendages, belonging to the phylum Arthopoda. Crabs have a segmented body.18. deciduous leaf
18. deciduous - a plant having foliage that is shed annually at the end of the growing season. This is an deciduous tree, as you can see it is several leaves, take your pick.
Actin
Actin has many functions, but one is the use as a scaffold for myosin which converts chemical energy into mechanical energy inside the muscle cell, allowing for muscle contractions. Such is an example of my friend sticking out her tongue.
Parenchyma cell
Parenchyma cells are relatively unspecialized plant cell type that carries out most of the metabolism, synthesizes and stores organic products, and develops into a more differentiated cell type. This is a picture off flowers that have parenchyma cells.Connective Tissue
Connective Tissue is any biological tissue that binds, protects, or supports organs. Its composed of collagen and elastin, the latter of which is an important component for ligaments and skin. These fingers with skin have connective tissue.
Mutualism
Mutualism is a symbolic relationship in which both participants benefit. This is a picture of a pond in a park in Gatlinburg,TN. The ducks benefit because it is an environment that they like living in, while humans that visit get the benefit of seeing a nice view and also getting a exercise, because the park is huge.17. adaptation of plant
This moss plants stays in moist, dark places. Thts why its in the dark shaded tree area. Because they are nonvascular
Adaptation of an animal
16. to adapt to my surroundings say for as an instant its cold in my house, i use a jacket and hat to warm myself up.
Steam-woody
Woody stems are the stems of plants who have been growing for two years or more. This is a picture of a woody stem of a plant in my yard.
Meristem
Meristem is the tissue in all plants, and found in zones where the plant can grow. Similar to function in stem cells, meristem is what makes this tree grow.
Decidous leaf
A decidous leaf is a leaf that falls off or shed at a specific season or stage of growth. This is a picture of a decidous leaf.
Ethylene
Ethylene is a gaseous organic compound with the formula C2H4. It is flammable, colorless at gas temperatures above 51.3 degrees and smells toxic. This is a picture of alchol in which it is found.
Gibberellins
Gibberellins are plant hormones that regulate growth and influence various developmental processes like germniation. This is a picture of a plant in my kitchen.
Keratin
Keratin is a type of protein found in the skin, hair, and nails. This is a picture of my grandmother's hair, which has keratin in it.
monocot
A monocot has one cotyledon like a corn seed....this is a picture of some corn. A corn seed has one seed coat but doesn't slip off easy.
Leaf- Gymnosperm
Conifer trees are in the category of gymnosperm due to that it's seed bearing. This makes it so that this pine tree is a gymnosperm tree as well.
Connective tissues
Connective tissues surround and support living cells. Skin is a great example of connective tissue. This is a picture of my leg .
Gymnosperm leaf
A gymnosperm leaf produces seeds as well as the gymnosperm cone. They develop on the surface of a scale. This is a leaf i found in my backyard.
