02 Plant Anatomy

Question 1

Body systems for Plants

Answer 1

Shoot system and root system

Question 2

Shoot System

Answer 2

All parts above ground

Question 3

Root System

Answer 3

All parts below ground

Question 4

Shoot System Organs

Answer 4

-Stem
-Leaves
-Flower/Fruit

Question 5

Root System Organs

Answer 5

Roots

Question 6

Root System Organs: Roots

Answer 6

-Anchor plant in soil
-Makes sure it doesn’t fall over
-gains water from soil and moves to stem
-Stores food made in other parts of plant

Question 7

Shoot System Organs: Stem

Answer 7

-transports water and nutrients throughout plant
-supports rest of the shoot system

Question 8

Shoot System Organs: Leaves

Answer 8

Converts light energy into the chemical energy of food through photosynthesis

Question 9

Shoot System Organs: Flowers

Answer 9

-Reproductive structure of plant
-Produces seeds through sexual reproduction

stomena: male organs -> consist of anther and filament -> produce pollen (male sex cells)

pistil: female organs -> consist of ovary, style, and stigma ->eggs located in ovary (female sex cells)

When pollen and an egg unite, the fertilized egg becomes a seed

Question 10

Major Plant Tissues

Answer 10

1)Dermal/epidermis tissue
2) Ground tissue
3) Vascular tissue
4) Meristematic tissue

Question 11

Major Plant Tissues: Dermal tissue/epidermis

Answer 11

-forms covering over plant’s organs
- by this, protects inner tissues from damage
-consists of epidermal cells including guard cells

Question 12

Major Plant Tissues: Ground tissue

Answer 12

Consists of: Parenchyma cells, Collenchyma cells, Sclerenchyma cells

Question 13

Major Plant Tissues: Vascular tissue

Answer 13

Consists of:
-xylem cells: moves water up to plant
-phloem cells: moves sugars when needed growth and metabolism

Question 14

Major Plant Tissues: Meristematic tissue

Answer 14

-responsible for plant growth
-Made of meristematic cells (undifferentiated cells that can become any cell)

Question 15

The growth of plant tissues

Answer 15

-Rapidly dividing meristematic cells at the tips of roots and branches cause upward, downward and outward growth of plants
-A bud is a swelling of the stem that contains the meristem for new tissues
-Most active growth occurs near the terminal bud (top of the plant or ends of the roots)
-The lateral buds are dormant but can give rise to new branches, leaves and flowers
