What are the 6 structures of a seed plant?
Seed, Roots, Stem, Leaf, Flower, Cone
What is the word equation for photosynthesis?
Energy (from the sun) + Carbon Dioxide (CO2) + Water (H2O) = Sugar + Oxygen
What are pollinators and give an example.
Pollinators = Organisms that carry pollen from one flower to another.
Examples include birds, bees, insects.
How can the flower part of a plant adapt to its environment?
For example, bright coloured petals help to attract pollinators like birds, bees etc.
What are the 4 optimal conditions for plant growth?
Light, Water, Nutrients and Space
What is the 3 stages of the seed plant life cycle?
Seed, Seedling, Adult
What is diffusion and give an example.
The movement of particles from an area of high concentration to an area of low concentration.
Occurs until the concentration is equal on both sides (evenly dispersed)
Examples: Putting food colouring into water.
What are the male and female parts of a flower called?
Pollen (male) and Ovary (female). The ovary contains the ovules.
Inherited behavioural or physical characteristics that help an organism to thrive and reproduce in its environment is called __________.
Provide an example of a plant that requires a large amount of space to grow vs. a plant that requires little space to grow.
Ex. A tree vs. a flower
What is the function of the root?
- Absorb water and nutrients from the soil.
- Support and anchor the plant.
- Store food to help the plant live in times of scarcity.
What is transpiration?
The evaporation of water from the surface of the plant - mainly from the leaves.
List 4 ways plants can grow without seeds.
- Runners
- Rhizomes
- Suckers
- Tubers/ Bulbs
- Cuttings
- Graftings
What kind of roots are you more than likely to find in dry desert conditions?
Taproots because these types of roots can get water deep down in the soil.
What are the raw materials of cellular respiration? What are the products?
Raw Materials = Sugar + Oxygen
Products = Energy + Carbon Dioxide (CO2) + Water (H2O)
Where in the plant does photosynthesis take place? What is this called?
It occurs in the leaves of a plant, in cells called chloroplasts.
What is Capillary Action?
Water travels from the roots to the leaves through tiny tubes in the roots and stems. The water particles are attracted to each other.
This term is used to describe the development of a seed into a new plant.
Germination
What structure of the tree has to adapt in order to reach optimal sunlight?
The stem.
What occurs during the seedling stage in the life cycle of a plant?
Where do the seedling plants get their nutrients?
Plants in the seedling stage grow very fast and produce new leaves, roots, and stems.
Seedling plants produce their own food by photosynthesis, but they also need nutrients from the soil to build their new parts.
What are the 2 different types of roots we discussed in class? Draw a diagram on the whiteboard to help explain your answer.
Taproot - Long major root that grows deep in the ground; smaller root hairs come out of it.
Fibrous Root - Clumped, matted roots that don’t grow deep; quick absorption
Osmosis is the movement of water particles across a _____________.
Cell Membrane / Semipermeable Membrane
Describe how pollinators help in the process of pollination?
Pollinators come to a flower in search of nectar, a sugary liquid that they eat. As the animal enters the flower, it becomes coated in pollen. When it leaves, it takes this pollen with it and transports it to the next flower.
Why do some plants have needle-like leaves instead of just regular leaves?
In dry environments, you may find thin needle-like leaves to protect the tree from drying out because it decreases water loss.
What are the five main nutrients that plants need?
Nitrogen, Phosphorus, Potassium, Calcium, Magnesium
