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
