  • After fertilization of an angiosperm seed, what does the ovary become?
    Fruit!
  • How do stolons grow? An example?
    These are stems that grow parallel to the ground. They can grow roots and produce a new plant. Example: strawberry
  • What are the four types of asexual production?
    Tubers, Stolons, Bulbs, Rhizomes
  • What is Geotropism?
    Gravity stimulus. The root grows towards gravity and the stems grow away from it.
  • What happens inside of leaves? (Hint: 2 Things)
    Where photosynthesis occurs and capture of carbon dioxide
  • What does the stomata do?
    Microscopic holes where carbon dioxide and water vapor and move in and out.
  • What does are the duties of the stem. (Hint: 3 things)
    Supports the plant. Vascular tissues pass through it. Stores substances.
  • What are the stamens?
    These produce the male gamete in flowers.
  • What is the green pigment inside chloroplasts?
    Chlorophyll
  • What do stamens in a flower produce?
    Pollen grains.
  • What do angiosperms have that gymnosperms don't?
    True flowers and fruit.
  • What is Thermonasty?
    The stimulus is temperature. Some flowers open their petals when the temperature rises and close them when it decreases.
  • What are two examples of a gymnosperm?
    Stone pine, prickly juniper, fir
  • The stimulus is a chemical substance, such as water. When there is no water, plants close their stomata to prevent the loss of water vapour.
    Chemonasty
  • How does pollination occur in angiosperms?
    Pollen is carried from the stigma of one flower to the stigma of another by the wind or animals.
  • What are the four nastic movements?
    Photonasty, Seismonasty, Chemonasty, Thermonasty
  • What is raw sap made of?
    Mix of water and mineral salts.
  • What is Thigmotropism?
    Physical contact stimulus. Some plants wind their stems around an object.
  • What are the four different tropic movements?
    Phototropism, Geotropism, Hydrotropism, Thigmotropism
  • Where are seeds formed inside of gymnosperms?
    Cones
  • What is the pistil?
    Part of a flower that produces female gametes.
  • Where does fertilization occur in gymnosperms?
    Female Cones
  • Light stimulus. Some flowers open during the day, in sunlight, and close at night.
    Photonasty
  • What are the duties of the roots? (Hint: 3 things)
    Roots fix the plant to the soil, they absorb water and mineral salts, can store substances.
  • What is Seismonasty?
    This is a sudden response to tactile stimulus. For example, the response of the carnivorous plant when an insect touches it.
  • What do vascular tissues do?
    Transport the sap around the plant.
  • Water stimulus. The roots grow in search of water or humid areas. .
    Hydrotropism
  • How do bulbs grow? An example?
    These are underground stems inside fleshy leave. The leaves store nutrients. Each bulb can produce a new plant. Example: Onions
  • How do rhizomes grow? An example?
    These are underground stems. They can produce new plants. The lily & ginger is an example.
  • Plants take in water and mineral salts through the ___________ ___________ in their roots.
    absorbent hairs
  • True or False: Male and female cones cannot be on the same plant.
    False
  • How is elaborated sap transported?
    Along vascular tissues, called phloem vessels.
  • How do tubers grow? An example?
    These are thick underground stems. They store nutrients and can produce a new plant. Example: potato
  • What's the difference between tropic and nastic movements?
    Tropic movements create a permanent change and nastic movements are temporary change.
  • How does pollination happen in gymnosperms?
    pollen from male cones is carried by the wind to female cones.
  • What is elaborated sap?
    Mix of water and organic matter produced during photosynthesis.
  • This is a stimulus to light. The stems grow towards the light and the roots grow away from it.
    Phototropism
