Biology, Unit 2, Leitner

Question 1

**fungi

Answer 1

any of a group of spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.

Question 2

**spores

Answer 2

A typically one-celled, reproductive unit capable of giving rise to a new individual without sexual fusion, characteristic of lower plants, fungi, and protozoans.

Question 3

**Yeast

Answer 3

a microscopic fungus consisting of single oval cells that reproduce by budding, and are capable of converting sugar into alcohol and carbon dioxide.

Question 4

**Algae

Answer 4

a simple, nonflowering, and typically aquatic plant of a large group that includes the seaweeds and many single-celled forms. Algae contain chlorophyll but lack true stems, roots, leaves, and vascular tissue.

Question 5

**Photosynthesis

Answer 5

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Question 6

**hydrophyte

Answer 6

a plant which grows only in or on water.

Question 7

**Photosynthesis equation

Answer 7

The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen. … In most plants, water is supplied from the roots, with the leaves collecting carbon dioxide via the stomata and sunlight captured by the chloroplasts in the leaves.

Question 8

**chlorophyll

Answer 8

a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring.

Question 9

**frond

Answer 9

on a seedless vascular plant, the leaf or leaf like part

Question 10

**angiosperm

Answer 10

a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees.

Question 11

**pollination

Answer 11

the transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization.

Question 12

**root

Answer 12

the part of a plant which attaches it to the ground or to a support, typically underground, conveying water and nourishment to the rest of the plant via numerous branches and fibers.

Question 13

**stem

Answer 13

the main body or stalk of a plant or shrub, typically rising above ground but occasionally subterranean.

Question 14

**leaf

Answer 14

a flattened structure of a higher plant, typically green and blade-like, that is attached to a stem directly or via a stalk. Leaves are the main organs of photosynthesis and transpiration.

Question 15

**flower

Answer 15

the seed-bearing part of a plant, consisting of reproductive organs (stamens and carpels) that are typically surrounded by a brightly colored corolla (petals) and a green calyx (sepals).

Question 16

**seed

Answer 16

a flowering plant’s unit of reproduction, capable of developing into another such plant; protects and nourishes young plant

Question 17

**cotyledon

Answer 17

seed leaves that provide food for the plant

Question 18

**dicot

Answer 18

One of the two classes of angiosperms: Seeds have two cotyledons, leaves with branching veins, flower parts in fours or fives, bundles of vascular tissue are in a ring.

Question 19

**germination

Answer 19

sprouting of seeds - occurs with right conditions of moisture, air, and temperature

Question 20

**monocot

Answer 20

One of the two classes of angiosperms: Seeds have one cotyledon, leaves with parallel veins, flower parts in threes, bundles of vascular tissue are scattered.

Question 21

**gymnosperm

Answer 21

Seed plants that do not have flowers or fruit; seeds usually protected by a cone.

Question 22

**deciduous

Answer 22

trees that lose all leaves around the same time each year

Question 23

**evergreen

Answer 23

trees that shed leaves year round, but always have some leaves
