Plant Relationships

100

What is the name of a relationship a plant has with another plant or even an animal?

Symbiotic Relatioship

200

What is something a plant "does" to keep butterflies from laying eggs on its leaves?

AND - Why is this important?

The leaves grow false eggs so the butterfly thinks someone else has already laid eggs on that leaf. This keeps the leaf from being destroyed by the caterpillars as they eat and grow. 

300

Plants produce what essential element we breathe?

Oxygen

400

Why are plants important to the ecosystem?

Producers - food for animals, food chains, produce oxygen etc

500

What happens to a flower that is cut from the stem of a living plant? Why?

It dies because it cannot survive without all of its working organs. 

Photosynthesis

100

This process allows plants to use energy from the _________ to make food.

sun

200

This part of the plant is the best at causing photosynthesis.

the leaf

300

What is the sun's energy converted to so the plant may have food?

Sugar

400

This organelle is located inside a plant cell and is responsible for photosynthesis.

Chloroplasts

500

Why are leaves and plants green? What causes this to be so?

Chlorophyll located inside the chloroplasts.

Plant Reproduction

100

Plants reproduce using which to main methods?

Asexual reproduction and sexual reproduction

200

What little particles, formed on the stamen, must be transported to other plants for sexual reproduction?

Pollen

300

All flowering plants begin life as what?

Seeds

400

Evergreen trees are called ____________ because their seeds are housed in cones, not fruits

conifers

500

How does asexual reproduction work in plants?

Plants shoot off leaves that attach themselves to the soil and then create a root system and new plant. Some plants, like carrots, grow from an old vegetable to produce new plants. 

Plant and Seed Parts

100

Name the three main plant parts. 

Leaf, stem, and roots

200

What is the name of the outside of a seed?

Seed coat

300

The "baby plant" inside the seed is known as what?

The embryo

400

Explain the difference between a taproot and fibrous roots

Taproot - single or central root going deep into the soil

Fibrous roots - long, thin roots that resemble fibers

500

The roots gather water and minerals, while the chloroplasts in the leaves create food for the plant. What are two special tissues surround the pith and transport the water, minerals, and food?

xylem - transports minerals and water

phloem - transports food

Plant Growth

100

Name the three things seeds must have to begin growing.

Air, sun (or the right temperature), and water

200

A seed is considered ____________ when it is just a dry seed waiting to grow.

Dormant

300

The eggs of the plant are stored in what?

The ovary

400

Name 2 signals that tell plants which directions to grow

Gravity and the sun

500

List the 5 steps of the life cycle of flowering plants.

- A seed is released when the fruit of the plant falls off the plant

- The proper conditions allow the seed to begin growing

- A small plant (seedling) emerges from the seed and begins growing

- The plant matures and develops an ovary where eggs are stored

- The ovary is fertilized and becomes a seed in the fruit.
