Question 1

Name the 3 main types of plant cells.

Accepted Answer

Parenchyma Cell
Collenchyma cells
Sclerenchyma Cells

Question 2

Parenchyma cell functions and an example of where these cells are found.

Accepted Answer

They are flexible, thin walled cells found through the plants and they are found in potatoes.

Question 3

Collenchyma cell functions and an example of where these cells are found.

Accepted Answer

They are often elongated and occur in long strands or cylinders that provide support for the surrounding and they are found in celery.

Question 4

Schlerenchyma cell functions and an example of where these cells are found.

Accepted Answer

They lack a cytoplasmic and has thick rigid cell walls and they are found in pears.

Question 5

Name the 4 main types of plant tissues.

Accepted Answer

Meristematic tissues
Dermal Tissues (The skin of the plant)
Vascular tissues
Ground tissues

Question 6

Describe meristemic tissues.

Accepted Answer

They are regions of rapidly dividing cells. 
Apical meristems
intercalary meristems
lateral meristems

Question 7

Describe dermal tissues.

Accepted Answer

The outer layer coverage of the is the epidermis.Most epidermal cells can create a fatty substances that form a cuticle.stomata  ( small opening that exchanges gases) Trichomes hairlike particles. Root hairs increase a roots’s surface area.

Question 8

Describe vascular tissues.

Accepted Answer

Xylem---transports water away from the roots

Phloem- -Transports dissolved sugars and other organics compound through the plant.

Question 9

Describe ground tissues.

Accepted Answer

functions include photosynthesis, storage, and support
most common type of tissue found in plants.

Question 10

Describe root functions.

Accepted Answer

It is the first to appear out of the seed
roots take out water and dissolved minerals
They anchor the plant

Question 11

List the layers of the root from the outside inward.

Accepted Answer

tip of the root is covered by a root cap.
The epidermal 

the cortex

ground tissues

endodermis
pericycle
he vascular tissue

Question 12

Describe the functions of stems.

Accepted Answer

provide support 
transport water into dissolve substances
and store food and water.

Question 13

Explain herbaceous and woody stems.

Accepted Answer

herbaceous stems
are soft flexible green stems
woody stems
have taught cork like tissues
stems have vascular bundles
in monocots the bundles are scatter and in dicots they are in a ring

Question 14

Describe the functions of leaves.

Accepted Answer

main function a a leave is photosynthesis
the flat part of the leaf is called a blade
the blade is attached to a petiole and that is how it is connected to the stem
Water evaporates from the leaf by transportation

Question 15

Name the 4 plant hormones.

Accepted Answer

Auxin
Gibberelins
Ethylene
Cytokenins

Question 16

Describe auxins and how they affect a plant.

Accepted Answer

t stimulates the lengthening of cells
it affects the rate of growth in roots, stems, and leaves. It it causes fruits to drops from plants when they raught
causes apical dominance which makes the plant grow mostly upward.

Question 17

Describe gibberellins and how they affect a plant.

Accepted Answer

causes cell elongation, stimulates cell division and affect seed growth
causes an increase of height

Question 18

Describe ethylene and how they affect a plant.

Accepted Answer

its the only gas hormone
it helps with the ripening of fruits, it soften and sweeten than unripe fruits
they found in plant tissues such as ripening fruits, dying leaves, and flowers

Question 19

Describe cytokinins and how they affect a plant.

Accepted Answer

they promote cell division by stimulating the production of the proteins needed for mitosis and cytokinesis
produce in rapidly dividing cell
when used in combination of auxin it causes rapid growth of the plant

Question 20

Describe a nastic response and give 2 examples.

Accepted Answer

it responses of a plant that causes movement independent of the direction of the stimulus. EX. sunflowers plant following the sun during the day
closing of a Venus flytrap’s leaves

Question 21

Describe tropic response.

Accepted Answer

where the plant reacts to light caused by an unequal amount of auxin
phototropism reacts to the light
gravitropism is a response of gravity,

Question 22

Name and describe three tropisms.

Accepted Answer

gravitropism is a response of gravity, 
roots grow with gravity so they have a positive gravitropism.

Thigmotropism is a response to a mechanical stimuli
a vining plant will wrap around the post.
Thigmotropism growth toward point of contact.

Question 23

In stems, how are vascular tissues arranged for monocots and dicots?

Accepted Answer

if the vascular bundles circle near the edge of the stem it is a dicot. If the vascular tissues are scattered they are monocot.

Question 24

In roots, how are vascular tissues arranged for monocots and dicots?

Accepted Answer

In dicots, the vasular tissue is in the shape of a star while in monocots it form a ring around a central pith.
