Flashcards in Transport/Food Flowering Plants Deck (16):
1

Give an example of an monocotyledonous plant.

Grass /rose

2

How are veins arranged in the leaves of monocots?

Parallel

3

How are the veins arranged in the leaves of dicot plants?

Networked/ branched network

4

Water enters outermost cells of the root by osmosis. What does this tell you about the cell sap of the outermost cells?

Lower water concentration
Higher solute concentration

5

Where precisely is the xylem found in the stem of a young dicotyledonous plant?

In the vascular bundles next to phloem

6

Where is vascular tissue found in the root?

Centre of root

7

Give one function of ground tissue?

Strenght/support

8

What is the function of meristematic tissue?

Growth. This is where mitosis takes place

9

Explain how water enters root hairs and then passes to the vascular tissue.

Osmosis / soil water more dilute / cell to cell (by osmosis)

10

Give two features of xylem that facilitates upward movement of water.

Narrow walls / no cell contents

11

Name and briefly explain any two processes involved in upward movement of water in plants.

Root pressure: H2O in pushes H2O up
Transpiration: H2O out pulls H2O up ( creates tension)

12

Explain how water enters the plant.

By osmosis/ when water moves from area of high water concentration through a semi - permeable membrane.

13

Do minerals enter the plant by the process of osmosis?

No/ only water moves by osmosis

14

How is xylem adapted for its role in water transport?

Lignified walls/ tubular lumen

15

Give account of cohesion model.

Water evaporates in leaf / water column hard to break continuous stream

16

What is meant by the term monocotyledon?

One seed leaf
