Classifying Organisms

Scientists classify animals and non-living things into groups according to their features or characteristics to understand how animals compare with one another

3

Vertebrates - Animals that have a backbone


  • A backbone

  • Covering of skin that protects them

  • Skeleton inside their body

  • Muscles that help them move

  • Blood moves through tubes

  • Lungs or gills for breathing

4

Multiple Select

Which one(s) are vertebrates?

1
2
3
4

5

  • Birds are NOT mammals because they lay eggs

  • They are covered with feathers

    • Most can fly, but some cannot (penguins)

Warm-blooded

Birds

  • Give birth to live babies (do not lay eggs)

  • Mothers produce milk to feed their babies

  • Mammals are warm-blooded: their bodies produce heat

  • Have fur, or hair that helps keep them warm

Mammals

Vertebrates are classified into five different groups

6

  • Live on land and breathe with lungs

  • Covered with scales and live in warmer climates

  • Reproduce by laying eggs

  • Their body temperatures change with their surroundings

  • Ex: snakes, lizards, turtles, 

alligators, crocodiles


Reptiles

  • Live in water and breathe with gills

  • Fish have scales to protect their bodies

  • Cold-blooded – their bodies are the same temperature as their surroundings

  • Reproduce (make more of their kind) by laying eggs in water

Fish

7

  • Live in water and breathe with gills when they are young 

  • As they become adults, they spend more time on land

  • Breathe with lungs when they are adults 

  • All amphibians are cold-blooded

  • Ex. Frogs, toads, newts, salamanders

Amphibians

14

Multiple Choice

How do we classify organisms?

1

We group them together according to their shared characteristics

2

We group them together according to their unique characteristics

3

We classify them based on when they appeared on Earth

4

We classify them based on their size

15

Invertebrates - animals that do not have a backbone

  • 90% of all animals are invertebrates! 

  • Tend to be small because they do not have a backbone

  • Many live in the ocean because the water helps support their weight 

  • Some have a hard covering or shell on the outside of their bodies for protection

    • Insects, spiders, crabs, snails, clams

16

Classifying Plants

There are 2 major groups of plants: vascular and nonvascular 

  • Vascular plants have tubes that carry water and nutrients to different parts of the plant 

  • Vascular plants can grow to different heights

  • Non-vascular plants do not have systems of tubes. They absorb water from their surroundings 

  • Non-vascular plants cannot grow higher than a few centimeters off the ground

  • Angiosperms are flowering plants

  • Gymnosperms do not use flowers for reproduction


  • Plants do not have fur, scales, or blood like animals. So how are they classified? 

They are divided into two groups: vascular and  nonvascular

17

Multiple Choice

_______________ produces flowers and seeds protected by fruit.

1
Angiosperms
2
Gymnosperms
3
Mosses
4
Ferns

18

Multiple Choice

How do vascular plants get water?

1
Vascular plants get water through their roots, which absorb it from the soil.
2
From nearby rivers and lakes through their flowers.
3
By absorbing moisture from the air through their stems.
4
Through their leaves during photosynthesis.

19

Multiple Choice

How do non-vascular plants get water?

1

Through root systems

2
By storing water in leaves
3
From symbiotic relationships with fungi
4
Non-vascular plants get water through direct absorption from their environment.

20

Vascular Plant Structure

  • Vascular plants have 3 main parts: roots, stems, and leaves

    • Roots: take in water and nutrients from the soil

    • Stems: move water and nutrients from the roots to the leaves

Leaves: capture the energy of the sunlight and use it to make food for the plant

21

media
  • Plants use sunlight to make food through photosynthesis

    • Take in water 

    • Take carbon dioxide from the air

    • A green material called chlorophyll traps the sunlight in leaves

    • Energy of the sunlight changes water and carbon dioxide into sugar and oxygen

Plants use the sugar for food and release oxygen into the air as waste

Photosynthesis

22

  • Plants that do not have tubes

    • These plants soak up water and food from the soil, like sponges

    • These plants are much smaller because they have to be touching the soil

    • Ex. Moss and Liverworts

Nonvascular (lower plants) 


  • Vascular means “having tubes” 

    • Have tubes that carry water from their roots to leaves 

    • When the weather is dry, plants use up the water in their tubes

    • Then, their stems get limp and the plants wilt

    • Examples: trees, grasses, and most garden plants

Vascular Plants (higher plants)

23

  • You can also group plants by the way they reproduce (produce new plants)

  • Plants reproduce by: 

    1. Producing seeds 

    2. Producing  cones

    3. Producing spores

24

Producing Seeds or Cones

Pine trees produce cones, but no flowers

  • The cones contain pollen, which animals spread from cone to cone

  • The trees’ seeds form into cones

25

Producing Seeds or Cones

  • Plants first produce flowers with pollen in them

    • Pollen is a special dust that helps plants reproduce

    • Bees, birds, bats, and the wind carry pollen from one plant to another

    • After plants receive pollen, they produce seeds

26

Multiple Choice

Question image

What is photosynthesis?

1
Photosynthesis is the process by which green plants convert light energy into chemical energy.
2
Photosynthesis is the conversion of chemical energy into light energy.
3
Photosynthesis occurs only in the dark.
4
Photosynthesis is the process of respiration in animals.

27

Multiple Choice

Which is not a way to group plants by they reproduce?

1

seeds

2

cones

3

soil

4

spores

28

  • Deciduous Plants: trees that lose its leaves in the winter

  • Coniferous Plants: plants that form seeds in cones

    • These trees keep their leaves in winter

Seeds and Cones

29

Producing Spores

  • Some plants do NOT produce flowers, pollen, seeds, or cones

  • Instead, they produce spores

    • A tiny cell that can grow into a plant

  • Spores drop off the plant into the soil, and then a new plant grows

    • Ferns and Moss

30
