1

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

Algae and fungi

2

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

Lichens

3

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

Fungi

4

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

Ferns

5

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

Gymnosperms

6

Flowering plants that bear their seeds within fruits

Angiosperms

7

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)

Ovule (plant)

8

The plant equivalent of the umbilical cord

Funinculus

9

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.

Photosynthesis

10

A green colored magnesium containing pigment, essential to photosynthesis

Chlorophyll

11

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

The cell

12

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

Cell membrane

13

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)

Cytoplasm

14

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

Nucleus

15

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

Ribosomes

16

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

Mitochondrion

17

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

Golgi complex (Golgi Bodies)

18

Bodies with chlorophyll that carry out photosynthesis in plant cells

Plastids

19

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.

Digestion

20

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

Carbohydrates

21

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

Fats

22

Are broken apart to their constituent amino acids

Proteins

23

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

Villi

24

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

Stomach

25

Area where the majority of digestion and absorption occur

Small intestine

26

Where absorption occurs in digestion

The stomach and gastro-intestinal tract

27

An organ system that moves nutrients, gases, and wastes to and from cells, helps fight diseases, and stabilizes body temperature and pH to maintain homeostasis. Composed of the cardiovascular system and the lymphatic system.

Circulatory system

28

Humans have a _________ cardiovascular system, that is, the blood never leaves the network of arteries, veins, and capillaries.

Closed cardiovascular system

29

The main components of the human circulatory system

Heart, blood, and blood vessels

30

The circulatory system includes ___________ circulation, a loop through the rest of the body to provide oxygenated blood

Pulmonary circulation
