Title: Plants%20and%20Animals


1
Plants and Animals
  • All living things need air, water, food and
    space. All living things depend on each other and
    on the environment.
  • Plants are able to make their own food using
    energy of sunlight (photosynthesis). Animals are
    unable to make their own food.
  • Plants are unable to move from one place to
    another.
  • Animals can move from one place to another. They
    use their senses to guide their movement.
  • Plants and animals each go through their own
    unique life cycles.

2
Characteristics of Plants
  • Plants are green from a chemical called
    chlorophyll
  • Chlorophyll helps plants turn energy from the sun
    into food.
  • Plants are called producers because the make, or
    produce, their own food.
  • Plants have stiff cell walls that help them stand
    but prevents them from moving from place to place.

3
How Plants Meet Their Needs
  • Plants have three parts
  • Roots
  • Stems
  • Leaves

4
Leaves
  • Leaves make food through a process called
    photosynthesis
  • Pores in the bottom of the leaves absorb carbon
    dioxide and give off oxygen
  • In the leaves, sunlight is mixed with carbon
    dioxide to produce glucose, a type of sugar.
  • Photosynthesis also gives off water and oxygen.

5
Stems
  • Stems are the main body of the plant
  • Stems support the plants leaves and flowers.
  • Stems move water and minerals to the leaves, and
    food from the leaves to the roots.

6
Roots
  • Roots are the part of the plant usually found
    below the surface.
  • Roots hold the plant in place.
  • Roots absorb the water and minerals form the soil.

7
Life Cycle of Plants
  • The process all living things go through
  • Begin life, grow, age, and eventually die.
  • As living things age, they often go through
    changes.

8
Life Cycle of Plants
  • A seed lands on the ground
  • In good conditions, the seed germinates and roots
    push into the soil.
  • The seed sprouts and becomes a seedling.
  • The seedling begins to grow into a plant.
  • The plant develops flowers and produces pollen.
  • A new seed develops in the plant if it was
    pollinated.

9
Spreading Seeds
  • Seeds need to be spread away from their parent
    plant so that they dont compete for food.
  • Ways that seeds are spread
  • Blown by the wind
  • Moved by animals
  • Apply what you learned on page 56

10
How Animals Meet their Needs
  • Animals cannot make their own food.
  • In order to obtain energy, they must eat other
    plants or animals.
  • Animals are called consumers because they depend
    on eating, or consuming, other living things in
    order to survive.

11
Saltwater Environment
  • Fish use gills to filter water and get oxygen
  • Some fish have teeth and eat smaller fish for
    food
  • Many fish have flat bodies to allow them to rest
    on the seafloor
  • Some saltwater animals scrape the seafloor for
    something to eat.
  • These traits are called adaptations.

12
Freshwater Environment
  • Only 3 of Earths water is freshwater.
  • Only 1 is found in lakes, rivers, and wetlands.
    The reminder is stored as ice or groundwater.
  • The plants and animals found in freshwater eat
    other plants or animals.
  • Fish use gills to absorb oxygen just like other
    fish, but they cannot survive in saltwater.

13
Land Animals
  • Many types of land environments
  • Deserts
  • Tropical rain forests
  • Grasslands
  • Very cold places
  • Animals have special characteristics, or
    adaptations, to help them meet their needs

14
Land Animals
  • All land animals breathe oxygen form the air
    around them
  • Drink water
  • Move from place to place to find food
  • Usually have limbs to help them move.
  • Apply what you learned on page 57

15
Life Cycle of Animals
  • Reptiles and birds are born from eggs
  • Mammals have live births
  • Some animals go through special stages and change
    from one form to a completely different form,
    such as frogs.

16
Metamorphosis
  • A process in which an animal changes its physical
    form
  • Egg
  • Larva or caterpillar
  • Pupa or cocoon
  • Adult
