Description

Name: SECTION 4.1 – SYSTEMS IN PLANTS 1. Below is a diagram of a flowering plant. Label the indicated structures in the table below:

Structure

Function in the Plant System

A

Flower

Flowers are specialized structures developed for sexual reproduction.

B

Leaf

The leaf is the main photosynthetic structure of the plant.

C

Fruit

Fruits protect the seeds. The fruit serves as a physical barrier between the seed or seeds and the external environment during seed development.

D

Main stem

It supports the branches , leaves and flowers and provides a way to transport materials.

E

Shoot system

The shoot system is the system that is specialized for two main functions: to conduct photosynthesis and to produce flowers for sexual reproduction.

F

Root system

The root system is the part of the plant that typically grows below ground.

2. How do plants make their own food? Plants make their own food by photosynthesis. 3. Describe each of the following types of plant tissue systems: Plant Tissue System Description Dermal tissue system is made up of Dermal Tissue System tissues that form the outer surfaces of plant parts. The vascular tissue system is made up of tissues specialized for the Vascular Tissue System transportation of water,materials and nutrients throughout the plant. Ground Tissue System The ground tissues system makes up

Function The tissues covering the outer surface of the plant. the tissues are responsible for conducting materials within a plant.

all plant tissues other than those that

Name: all of the other structures within a plant.

make up the dermal and vascular tissue systems.

4. Answer the following questions about the leaf (the function should have already been written in the diagram labelling table): Write out the word equation for light energy + carbon dioxide + water chlorophyll→ glucose + oxygen photosynthesis: What organelle performs chloroplast photosynthesis? What are thylakoids? Chloroplasts contain flat ,disc like structures called thylakoids. What is a stack of thylakoids Grana called? What is the pigment that chlorophyll collects the light called? 5. Answer the following questions about the flower (the function should have already been written in the diagram labelling table): What is pollen, and what does The male reproductive structure produce pollen grains and eggs are pollen fertilize? fertilized by pollen. What is formed after After pollination the female flower parts form seeds. pollination? What are seeds contained In most flowering plants, the seeds are contained within a specialized within? structure called a fruit. What is a stack of thylakoids Grana called? What is the pigment that Chlorophyll collects the light called? What are the two main There are two types of pollination, called self-pollination and crossmethods of pollination? pollination. What are cones? Coniferous plants are not flowering plants. 6. Answer the following questions about the stem (the function should have already been written in the diagram labelling table): In trees, what is the name of the trunk stem? What is the function of the The stem contains significant amounts of vascular tissues for carrying vascular tissue found in stems? substances to and from roots , leaves and fruits....
