Botany Exam 1

Front 1

Most important plant family

Back 1

grass family. 70 percent.

Front 2

What are the main organs of flowering plants?

Back 2

stems, roots, leaves, flowers.

Front 3

What are the two most important things in science?

Back 3

to observe and infer.

Front 4

Vacuole

Back 4

Recycling reservoir for some substances, and waste storage area for others; occupies most of the volume of a mature plant cell.

Front 5

Dictyosome

Back 5

Layers of flattened, membrane-bound sacs, functioning in secretion.

Front 6

Nucleus

Back 6

Large membrane-bound organelle containing the genetic material determining the cell's structure and function.

Front 7

Mitochondrion

Back 7

This organelle is much smaller in size than the chloroplast and releases energy.

Front 8

Cell Wall

Back 8

This part is a porous, nonliving, supportive, and protective shell of a plant cell.

Front 9

Endoplasmic Reticulum

Back 9

This part forms a continuous channel between the nucleus and plasma membrane.

Front 10

Cytoplasm

Back 10

Numerous membrane-bound, organized structures collectively called organelles are contained here.

Front 11

Ribosome

Back 11

Frequently found attached to the endoplasmic reticulum or scattered in the cytoplasm, functioning in the formation of protein.

Front 12

Plasma membrane

Back 12

Close to the cell wall, this very thin structure controls the movement of substances into and out of the cytoplasm.

Front 13

Chloroplast

Back 13

Numerous organelles containing green pigment responsible for the capture of light energy. Site of photosynthesis.

Front 14

Prophase

Back 14

The nuclear membrane and the nucleolus disappear in this phase, and the chromosomes first become visible during this phase.

Front 15

Interphase

Back 15

Chromosome duplication takes place during this phase.

Front 16

Anaphase

Back 16

During this phase the chromatids divide and move toward opposite poles.

Front 17

Telophase

Back 17

The nuclear membrane and nucleolus reappear in this phase.

Front 18

Metaphase

Back 18

All the pairs of chromatids gather at the equator during this phase.

Front 19

What is the difference between cytoplasm and protoplasm?

Back 19

The protoplasm does not have a nucleus.

Front 20

When vinegar was added to the plant cell what happened?

Back 20

The cytoplasm stopped moving.

Front 21

What are the different types of leaf tissues?

Back 21

Meristematic, ground, dermal, and vascular.

Front 22

Meristematic

Back 22

site of cell division. Without meristems, plants wouldn't grow.

Front 23

Ground

Back 23

constitutes most of the primary body of a plant. Functions: storage, metabolism, and support.

Front 24

Dermal

Back 24

forms the epidermis that covers the plant body.

Front 25

Vascular

Back 25

the plant's plumbing system, like long pipes that spread throughout a plant.

Front 26

What are the different types of Leaf cells?

Back 26

collenchyma, schlerenchyma, parenchyma

Front 27

Collenchyma

Back 27

long cells that support growing regions and are common in expanding leaves, petioles, and elongating stems.

Front 28

Schlerenchyma

Back 28

rigid cells that produce thick, nonstretchable, secondary cell walls. Support and strengthen non growing, non extending regions of plants such as mature stems.

Front 29

Parenchyma

Back 29

most abundant and versatile cells in plants. Identified by inconspicuous structure (not distinct).

Front 30

Stomata

Back 30

specialized structures in the epidermis. Abundant on the undersides of leaves. Allow CO2 to enter the leaf and fuel photosynthesis.

Front 31

What are the phases of mitosis?

Back 31

Interphase, Prophase, Metaphase, Anaphase, Telophase.
