Life Science

These plants lack true roots, stems, and leaves. • range from single cell to seaweed • mostly inhabit lakes and oceans • fungi; molds, yeasts, mushrooms

Two different organisms (fungi and algae), living together symbiotically

These plants lack chlorophyll and thus cannot manufacture food; they are either parasites or saprophytes

These plants lack seeds and reproduce by means of spores. They do have stems, roots, and leaves. Spores develop into a new plant without fertilization

Cone-bearing plants (including pines) with seeds exposed on cone scales

Flowering plants that bear their seeds within fruits

Develops into a seed after plant reproduction. In seed plants, it is the structure that gives rise to and contains the female reproductive cells. -in flowering plants, it is located in the actual flower, the part of the carpel known as the ovary (which becomes the fruit)

The plant equivalent of the umbilical cord

A metabolic pathway that converts light energy into chemical energy. Plants use the energy from the sunlight to convert carbon dioxide from the atmosphere, plus water, to simple sugars.

A green colored magnesium containing pigment, essential to photosynthesis

The smallest amount of living matter; the unit of structure and function for all organisms

Semi permeable part of the cell that allows some substances to pass while excluding others

Main material within a cell, varies in consistency from a fluid to a semi solid. Consists of functional bodies such as centrosome, ribosomes, mitochondria, Golgi bodies, and vacuoles. (Also plastids in plants)

The organelle that contains the cells DNA and is the control center of the cell

The organelle in which amino acids are hooked together to make proteins

The organelle that breaks down food molecules to make Adenosine triphosphate (ATP). “The powerhouse of the cell”. Involved in signaling, cellular division, differentiation, and cell death

The organelle that processes and transports proteins and other materials out of the cell

Bodies with chlorophyll that carry out photosynthesis in plant cells

The breaking down of chemicals in the body into a form that can be absorbed; also the process by which the body breaks down chemicals into smaller components that can be digested by the blood stream.

Converted into various sugars by the action of several enzymes (including saliva and ptyalin)

Transformed into glycerol and fatty acids by the combined action of bile from the liver and the enzyme lipase from the pancreas

Are broken apart to their constituent amino acids

Millions of projections lining the small intestine that absorb the final products of digestion (sugars, glycerol, fatty acids, amino acids)

Here digestion occurs where food is broken down mechanically and chemically by churning and mixing the food with enzymes
