Plants and Animals

The goal is to be born, survive, and reproduce successfully!

Plant reproductive parts

• Nonvascular plants and seedless plants use spores

• Gymnosperms (pines and conifers) use cones

• Angiosperms (flowering plants) use flowers and fruit

A fern with spores

Spores are not seeds.

Angiosperm with flowers and fruit

Flowers attract pollinators with their color and scent.

Gymnosperm (pines and conifers) with cones

Cones are "naked" because they are not surrounded by fruit. Gymnosperm means naked seed.

Multiple Choice

Which of these is an angiosperm?

Multiple Select

What makes flowers so attractive to pollinators? (Choose all that are correct)

• bright colors

• strong scent

• sweet nectar

• deadly poisons

Flowers attract pollinators by adapting to meet the pollinators needs

Multiple Select

Bees need _____ for food; one to eat and one to carry home to the hive for baby bees.

• nectar and pollen

• flowers and fruit

• cones and spores

Multiple Choice

Which pollinator will only fly out at night to feed on night-blooming cactus flowers?

Flowers, once pollinated, make fruit. See the peach pit? It's a seed! Fruit protects seeds.

Multiple Choice

How does fruit help a flowering plant to reproduce successfully, besides protecting its seeds?

• It feeds the friendly farmers

• It gets eaten, so the seed is carried away by whatever eats the fruit.

• It hides the seed from predators.

Multiple Select

Which seeds are blown by the wind to be dispersed?

Squirrels are good at seed dispersal because they bury the oak tree seed called acorns to store them for food.

Animal Reproduction and Adaptation

speaking of squirrels...let's look at their lives!

Adaptations to Survive

Squirrels who bury acorns for the winter when there is no food are more likely to survive. It's a behavioral adaptation.

cuttlefish males fight over females...this is a behavioral adaptation

one male cuttlefish protects several females so only he can breed with them

Multiple Choice

What advantage would it be for a smaller male cuttlefish to pretend to be female by changing his markings and behavior?

• He can sneak in with protected females

• He doesn't have to mate

• He can start more fights

Multiple Select

What type of adaptation is it when a small cuttlefish male pretends to be female?

• Physical adaptation

• Behavioral adaptation

Physical Adaptations

Sometimes your coloring can help you survive. Check out this picture. Where's the lizard?

Multiple Choice

Which word means "blends in with the surroundings by matching colors and patterns?"

• Camel Fox

• Camouflage

• Camero frogs

• Cam All Fogged

Multiple Select

Which pictures contain a snake? (check all that apply)

Obvious Snake

not so obvious snake

Spot the python nesting her eggs!

Can you see the nope rope (snake)?

Here is the snake!

If your amygdala is telling you to be afraid, your frontal lobe of your brain should remind you this is JUST A PICTURE. You are safe!

Now can you see the snake?

Poll

How many snakes did you see the before they were pointed out to you?

• 1

• 2

• 3

• 4

Sea turtles spend most of their lives in the sea.

Female turtles leave the sea once a year to go to the beach where they hatched from an egg.

Multiple Choice

What reason would a female sea turtle have for leaving the sea?

• To visit its mother

• To help the tourism at the beach

• To lay eggs in the sand

Multiple Choice

Why would a sea turtle lay eggs in the sand and cover them up?

• To keep the eggs warm, so they will eventually hatch

• To hide them from predators who eat the eggs

• To make it difficult for baby turtles to get to the sea, so only the strong survive.

Multiple Choice

Is laying eggs on a beach and covering them up a physical adaptation or a behavioral adaptation?

• Physical

• Behavioral

Multiple Select

A female turtle will leave her offspring and return to the ocean. How can she insure that some survive?

• Lay hundreds of eggs and hope a few survive.

• Leave instructions for the baby turtles to follow and stay safe

• Come back when they hatch to guard them while they try to get to the sea.

Whether it is a flower being pollinated or two butterflies mating, sexual reproduction requires two parents

Multiple Choice

Which statement is true about plant sexual reproduction?

• Pollen contains sperm and the egg is in the stamen on a new flower

• Pollen contains sperm and comes from the stamen

• Pollen contains eggs and butterflies transport them to new flowers
