A. Netted leaf venation and tap root
B. Two cotyledons
C. Circular arrangement of vascular tissues
D. Parallel lead venation and fibrous root system.

Question 7

TYPES OF PLANT CELLS:

Thin, primary walls that retain their protoplasm at maturity. Some of its functions are cells in leaves for photosynthesis and respiration.

Answer 7

Parenchyma cells.

Question 8

PLANT TISSUES:

Outer covering of the leaves, stems and roots

Answer 8

Dermal tissues

Question 9

Thin layer over the external part of the dermal tissue to prevent water loss; absent in roots

Answer 9

Cuticle

Question 10

Control water lost of transpiration; allows gas exchange

Answer 10

Stomata

Question 11

These tissues actively divide and is located at the tips (shoot and root)

Answer 11

Meristematic Tissues

Question 12

Female part of a flower

Answer 12

Pistil / Carpel

Question 13

This part of the (female) flower is the sticy part which catches the pollen

A. Style
B. Ovary
C. Stigma

Answer 13

C. Stigma

Question 14

What is the male part of a flower?

Answer 14

Stamen

Question 15

Which of the male part of a flower holds the anther (the one which releases the pollen) upright?

Answer 15

Filament

Question 16

During hot days, the guard cells close the stomatal pore. The main purpose of this is because:

A. High temp. Makes the stomata’s function irrelevant to the plant.
B. High temp. Makes CO2 enter the plant in other openings other than the stomata.
C. High temp. Makes H2O easier to leave the plants, so guard cells mame sure that the stomata is closed to prevent further water loss.
D. High temp. Drives H2O into the stomata, so guard cells make sure that the stomata is closed to prevent excessive water entry.

Answer 16

C.

Question 17

In Professor Geller’s plant anatomy class, the topic involves the fundamental tissues of plants. In their lesson, the tissue for photosynthesis is in question. Which of the ff is involved in photosynthesis?

A. Dermal tissue
B. Meristematic tissue
C. Ground tissue
D. Vascular tissue

Answer 17

C. Ground tissue

Question 18

Also known as phytohormones

Answer 18

Plant hormones

Question 19

Occurs when the pollen attaches to the stigma, elongates down the style, and releases two spermatozoa into embryo sac, which fertilizes the egg and polar nuclei

Answer 19

Pollination

Question 20

This plant hormone promotes seed dormancy and counters the effect of auxin.

A. Gibberelline
B. Ethylene
C. Abscisic acid
D. Cytokinin

Answer 20

C. Abscisic acid
