  • Explain the cycle of a flowering plant
    1. Seed dispersal 2. Germination 3. Growth 4.Flowering 5.pollination 6.Fruits with seeds
  • What happens with the oxygen and the carbon dioxide in the process of photosynthesis? And in respiration?
    Photosynthesis = carbon dioxide is transformed into oxygen (during the day) | Respiration = like humans ( day at night)
  • How is called the tiny openings in the leaves ?
    stomata.
  • How seeds can be dispersed in different ways?
    Seeds can be dispersed by birds, insects and other animals, wind or water.
  • Draw a angiosperm plant and label the parts
    Stigma, style, ovary, ovules , anther,filament, stamen, sepal ,pisti.
  • The leaves absorb…………from the air.
    Carbon dioxide
  • What is the photosynthesis?
    Is the process in which plants make their own food
  • The leaves contain a green substance called… and this traps…
    Chlorophyll traps sunlight.
  • When plants reproduce asexually, there is pollinatio or fertilisation. True or False why?
    False
  • Why ferns, angiosperms and gymnosperms are vascular plants?
    Because they have tubes called vessels to transport water and nutrients around the plant.
  • Elaborated sap is the plant's food. It travels from the leaves to all parts of the plant through tubes called…
    phloem vessels.
  • Angiosperms produce.......
    Flowers
  • During photosynthesis, plants use sunlight and carbon dioxide to..
    to transform raw sap into Elaborate sap
  • Some plants reproduce using parts of themselves. They create a new plant from these parts. This is called
    asexual reproduction.
  • Pollen can be dispersed in different ways. How is it?
    Pollen can be transported by birds, insects and other animals or the wind.
  • Plants absorb…………… how is called that mixture?
    water and minerals from the soil through their roots. This mixture of water and minerals is called raw sap.
  • A stolon grows horizontally above the ground. True or False
    True
  • Raw sap travels up the stem to the leaves through tubes called……
    xylem vessels.
  • • Mosses and ferns produce......
    spores.
  • Explain in which consists the Pollination?
    The pollen travels from the anther of one flower to the stigma of the same or a different flower. A pollen grain reaches an ovule in the ovary and fertilisation
  • Plants exchange gases through two different processes:
    Photosynthesis and respiration
  • Why do leaves change colour in autumn?
    In autumn, there is less sunlight, the level of chlorophyll decreases and the ‘autumn colours’ can be seen.
  • Explain the process of photosynthesis
    Book
  • The female reproductive organs produce.......and The male reproductive organs produce
    ovules/pollen
  • The upper side of the leaves contains More or less chlorophyll than the underside?
    More chlorophyll
  • How many types of plants which produce seeds are there?
    Two - angiosperms and gymnosperms
