photosynthesis

photosynthesis

The process in which plants use the energy of sunlight to make high-energy carbohydrates

adenosine triphosphate

a compound consisting of an adenosine molecule bonded to three phosphate groups, present in all living tissue.

ATP synthase

the enzyme that makes ATP molecules

chlorophyll

a pigment present in all green plants and a few other organisms.

photosystem

a biochemical mechanism in plants by which chlorophyll absorbs light energy for photosynthesis.

thylakoid

a disk-shaped, membranous sac containing chlorophyll, in which the light reaction of photosynthesis occurs, found in blue-green algae and in the chloroplasts of green plants.

autotroph

they make there own food

heterotroph

an organism that eats other plants or animals for energy and nutrients

capillary action

the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.

adhesion

the attraction of molecules of one kind for molecules of a different kind.

style

a structure found within the flower.

petal

modified leaves that envelop a flower's reproductive organs.

sepal

defensive organ that encloses and protects the developing reproductive structures.

pollen cone

small collection of cells that are part of the male part of the plant that assists with plant fertilization.

stamen

the male reproductive organs of flowering plants.

light dependent

convert light energy into chemical energy.

Calvin Cycle

the cycle of chemical reactions where the carbon from the carbon cycle is fixed into sugars.

NADP

a biological carrier of reducing equivalents

stigma

the part of the pistil where pollen germinates.

carpel

leaflike, seed-bearing structures that constitute the innermost whorl of a flower.

anther

comprises sac-like structures known as microsporangia which produce pollen for the process of pollination to occur.

xylem

plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.

phloem

plant vascular tissue that conducts foods made in the leaves during photosynthesis to all other parts of the plant.

ovary

enlarged basal portion of the pistil, the female organ of a flower.

pigment

any coloured material found in a plant or animal cell.

filament

a single thread or a thin flexible threadlike object, process, or appendage.

seed cone

are compact branching systems composed of reiterated units that typically consist of two separate structures: a bract, or modified leaf, that subtends an ovuliferous scale, which is a modified seed-bearing shoot

stroma

the cells and tissues that support and give structure to organs, glands, or other tissues in the body.
