EOC Review - Day 1 - Plant/Animal Systems

This review is self-paced, but we may go through parts of it together in class.

​

Please make sure you finish. This review counts as a grade.

Plant Body Systems

Plants only have two body systems: Roots and Shoots

​

Roots are below ground.

​

Shoots are above ground.

Root system

​

1. Brings in water and nutrients from the soil

​

2. Anchors and stabilizes the plant

Shoots System

1. Leaves (conduct photosynthesis)

​

2. Stems (store & transport water & nutrients)

​

3. Flowers / fruits / cones (reproduction)

Vascular Tissues in Plants

Vascular tissues in plants are similar to the circulatory system of animals. They both carry water, nutrients, and wastes throughout the body.

​

Plants have two types of vascular tissues:​

a. Xylem ​

b. Phloem 

Xylem

a. Xylem (non-living; transports water)​

​

How to remember xylem transports water?

​

THINK!  Water and XYlem… like your abc’s! WXY(Z)

Phloem

b. Phloem (living; transports nutrients / sugar)​

​

How to remember phloem transports nutrients?

​

THINK!

​

Nutrients = Food and Phloem… 

Food and phloem both start with “F” sound!

Tropism

Tropism is directed growth in response to a stimulus.

​

One type of tropism is phototropism.

​

Phototropism: a plant's response to light.

Tropism

Thigmotropism: A plant’s response to touch

​

Examples: Vining plants, Venus fly trap, Touch me not (sensitive plant)

Tropism

Geotropism (a.k.a. gravitropism) = a plant's response to gravity.

Roots go down, shoots go up.​

Multiple Choice

The plant in the image is growing towards sunlight and away from shade. What sort of tropism is this?

• Geotropism

• Phototropism

• Hydrotropism

• Thigmotropism

Plants: Sexual Reproduction

Stamen: male part of the flower.

It includes:

​

Anther - produces pollen (male gamete, or sperm)

​

Filament 

Plants: Sexual Reproduction

Pistil (Carpel): female part of the flower

It includes:

Stigma 

​Style 

Ovules - female gametes; fertilized by pollen

Pollination

Flower petals are often large, brightly colored and fragrant.

This is to attract POLLINATORS!

Pollination: The transfer of pollen from the anther to the stigma.

Common pollinators:

Hummingbirds, moths, bees, butterflies, bats, etc.

Feedback Mechanisms Maintain Homeostasis

Multiple Choice

After you eat, your glucose levels rise as nutrients enter the bloodstream.

When glucose levels are high, the pancrease releases the hormone insulin, which reduces blood glucose levels back to normal.

Which two body systems are most important in the homeostasis of blood glucose?

• Circulatory and reproductive

• Immune and nervous

• Endocrine and skeletal

• Circulatory and endocrine

Multiple Choice

• A

• B

• C

• D

Multiple Choice

Plants are vascular. What does vascular mean?

• They produce their own food through photosynthesis.

• They have a nucleus and organelles.

• They have vessels to transport materials throughout the organism.

• They cannot move freely.

Multiple Choice

Plants have two vascular tissues: xylem and phloem. What are the major differences between xylem and phloem?

• Xylem can only carry sugar downwards while phloem can only carry sugar upwards.

• Xylem carries nutrients throughout the plant and phloem only carries water upwards.

• Xylem carries water upwards and phloem carries nutrients throughout the plant.

• Xylem is only found in nonvascular plants while phloem is only found in vascular plants.

Multiple Choice

The sperm cell of the plant is the:

• Petals

• Pistil (carpel)

• Stamen

• Pollen

Multiple Choice

The part of the plant with the blue oval around it is the:

• Pistil / carpel (the male reproductive part)

• Pistil / carpel (the female reproductive part)

• Stamen (the male reproductive part)

• Stamen (the female reproductive part)

Multiple Choice

The part of the plant with the blue oval around it is the:

• Pistil / carpel (the male reproductive part)

• Pistil / carpel (the female reproductive part)

• Stamen (the male reproductive part)

• Stamen (the female reproductive part)

Multiple Choice

Flowers often have large, colorful, fragrant petals that open as they bloom.

What is the purpose of such petals?

• To attract potential pollinators.

• To warn animals they are poisonous.

• To deter potential predators.

• To communicate with other flowers.
