Answer 2

1. Seedless Plants

2. Two types of Seed Plants

Question 3

What are four common characteristics all plants share?

Answer 3

1. Cuticles 2.Photosynthesis
2. Cell Walls
3. Reproduction

Question 4

What is the need for photosynthesis to occur?

Where does it take place in the plant?

Answer 4

Chloroplasts captures the energy from sunlight to make food from carbon dioxide and water.

Chloroplasts are organelles that are found only in plant cells and some protist cells.

Question 5

Give some examples

Answer 5

1. Roots
2. Leaves
3. Stems
4. Seeds
5. Flowers
6. Fruits

Roots- Potato, Sweet Potato
Leaves- Lettuce, Spinach,Kale
Stems- Celery, Cinnamon 
Seeds- Peanuts
Flowers- Sugar Cane
Fruits- Tomato

Question 6

What are tropisms?

How do they work?

What controls tropisms?

Answer 6

The Meaning- growth in response to a a stimulus.

Work-

Question 7

Name the parts of the flower and what do each of them do?

Answer 7

1. Sepals
2. Petals
3. Stamen
4. Pistil
5. Ovary
6. Ovule

Sepals- are modified leaves that make up the outermost ring of flower parts and protect the flower while it’s a bud.

Petals- are broad, flat, thin leaflike parts of the flower.

Stamen- is the male reproductive structure of the flowers.

Pistil- is the female reproductive structure of flowers.

Ovary- the rounded base of a pistil that contains one or more ovules.

Ovule- contains an egg.

Question 8

Gymnosperms

Answer 8

Nonflowering seed plants

Question 9

Angiosperms

Answer 9

Flowering seed plants

Question 10

Seedless Vascular Plants

Answer 10

Don’t have seeds

Example: Ferns, Horsetails, and club mosses.

Question 11

Xylem

Answer 11

Vascular tissue that transports water and minerals through a plant.

Also: Xylem moves minerals from the roots to the shoots.

Question 12

Phloem

Answer 12

Vascular tissue that transports food molecules to all parts of a plant.

Also: Xylem and Phloem are found in all parts of vascular plants.

Question 13

Pollination

Answer 13

transfers of pollen from the male to the female.

Also: Pollination occurs during sexual reproduction.

Question 14

Monocots

Answer 14

1. Leaves with parallel veins
2. Flower parts in threes
3. One cotyledon
4. Bundles of vascular tissue are scattered.

Question 15

Eudicots

Answer 15

1. Leaves with branching veins
2. Flower parts in fours or fives
3. Two cotyledons(seed leaves)
4. Bundles of vascular tissue are in a ring

Question 16

The parts of a leaf

Answer 16

1. Cuticle
2. Stoma
3. Guard Cells
4. Vascular Tissue ( Xylem, Phloem)
5. Lower Epidermis
6. Spongy Layer
7. Palisade Layer
8. Upper Epidermis

Cuticle- covers the outer surfaces of a leaf.
