Flashcards in The Structure Of Flowering Plants Deck (14):
1

Function of roots

Anchor plant into the soil
Absorb water and minerals from soil
Store food eg carrots

2

Types of roots

Tap roots - form a triangular shape, numerous lateral roots emerge from tap root eg carrot

Fibrous root - a mass of equally sized branch roots eg grass

Adventitious roots - emerge from other parts of the plant


3

Root cap function

Protects root tip as it grows through soil

4

Meristem function

A zone of reproduction by mitosis (splitting cells)

5

What is the zone of elongation

Where cells become longer due to plant growth regulators

6

What is te zone of differentiation

Previously identical cells form new tissues here.
Root hairs also form here

7

What are the three type elf plant tissue

Dermal tissue - protective covering for plant

Vascular tissue - transport materials within plant eg xylem and phloem

Ground tissue - fills spaces between

8

Shoots consists of

Flowers
Leaves
Fruit
Seeds

9

Function of stems

Transport the aerial parts of the plant
Transport materials between leaves and roots
Store food

10

Which vascular tissue is towards the outside of the stem

Phloem

11

Function of leaves

Carry our photosynthesis
Exchange gasses
Allow water to pass out (transpiration)
Store food

12

Difference between monocots and dicots

Monocots have one cotyledon (food store) where as dicots gave two

Monocots are mainly herbaceous (without Woody parts) but dicots can be Both Woody and herbaceous

Monocots have long leaves, dicots have broad leaves

Monocots have parallel veins, dicots have branching veins

Monocots’ vascular tissues are scattered at random, dictots’ form a ring

Monocot flowers are in groups of three, dicots are in groups of four or five


13

Examples of monocots

Daffodils
Tulips
Grasses
Cereals

14

Examples of dicots

Beans
Peas
Oak
Elm
Ash
