Plants vs. Animals

Plants Animals

Rooted in one spot Mobile

Make their own food Go out and get their own food

Expel oxygen Breath out carbon dioxide

Cell Wall and chloroplasts No cell wall or chloroplasts

Plants are Important

Plants benefit animals in many ways

They give us

Medicine

Food

Fuel

Products

Oxygen

If you scratch my back I’ll scratch yours

Plants and animals both give what the other one needs

All animals need oxygen to survive, oxygen is produced by plants

All plants need carbon dioxide to make food, and animals breath out CO2

Making food

Plants have special components in their cells that are needed to make their own food, called Chloroplasts

A chloroplast is a green plastid inside a plant cell, it contains the pigment chlorophyll which is why plants are green.

This pigment is needed for plants to complete photosynthesis.

Photosynthesis is a process in which a plant makes its own food.

Gaining the right ingredients

Because plants can’t travel to get what they need they have their own way of doing things.

Colorful plants use their attractive looks to draw in insects to pollinate them

Plants also use the wind to disperse their seeds

Plant roots and leaves obtain the necessary ingredients for photosynthesis from the environment that surrounds the plant

Plant Roots and Leaves

Roots soak up water from the soil

Leaves take in carbon dioxide from the air surrounding the plant

Leaves have small openings on the surface that allows carbon dioxide to come into the plant and lets oxygen leave.

The small openings in the leaves are called Stomata. They can open and close according to the plants needs.

Photosynthesis

Process where plants take in H2O (water) and CO2 (carbon dioxide) and then light hits the chlorophyll and its starts to convert H2O and CO2 into Sugar and O2 (oxygen)

The sugar is what is needed by the plant

The O2 is not needed so it is released as a waste product into the atmosphere

Glucose

The sugar that is produced through photosynthesis is called Glucose

This is used by the plant in other processes so that is has energy and can grow

Cells

The reason plants can perform photosynthesis is because their cells are specially made for it.

Plants contain- Chloroplasts Chlorophyll The green pigment,

chlorophyll, is the reason most plants are green

Their color helps them absorb the strongest types of wavelengths to insure the best growing conditions

The cell wall

Plants also have a cell wall, it helps maintain their shape and supports them.

Some plant cells have a double cell wall that helps plants grow tall and sturdy.

The cell wall monitors what goes in and out

of a cell

Plants come in all shapes and sizes

There are so many different environments that plants grow in.

Plants adapt to their surroundings in order to survive

Plants in the rainforest have larger, broader leaves that are made for catching sunlight

Plants in the dessert have spines instead of leaves, and their stems are large to contain more water

Environmental affects

The reason plants have to adapt is for the environment their in

Many factors that affect plant growth are: Light intensity Temperature The soils pH

All over the world

Plants can’t always adapt and survive every where

Some are indigenous to the area

Some plants can be brought over from other countries and can thrive else where

The higher abundance of what a plant needs could lead to a highly plant populated area

The rainforest host thousands of different types of plants

Over view

Plants are important to animal survival

Plants can adapt to different environments

Photosynthesis is how plants grow and survive

Chloroplasts make photosynthesis possible

Plant cells are very similar to animal cells except they contain cell wall and chloroplasts

Plants are needed to balance ecosystems
