  • True or false. Photosynthesis => takes place in mitochondria cells
    False. Photosynthesis takes place in the chloroplasts of cells.
  • Indicates the name of the process and in which part it is carried out. C6H12O6 + O2 -> H2O + CO2
    Respiration, Mitochondria of cells.
  • Name the waste products that are eliminated in the excretion
    Gaseous products : Oxygen, Carbon dioxide, water vapour.
  • True or false. Plants respire all the time so they produces CO2 day and night.
    True.
  • True or false. The root is the organ that attaches the plant to the ground and absorb water and mineral salts
    True
  • All plants share the following characteristics :
    Eukaryotic plant cells; multicellular; autothophic organisms; reproduce sexually or asexually; live attached to a substrate.
  • Name the parts that appear in the nutrition function of plants
    Obtaining nutrients, Respiration, Distribution of substances, Excretion of waste
  • Indicates the name of the process and in which part it is carried out. H2O + Mineral Salts + CO2 + light -> C6H12O6 + O2
    Photosynthesis, Chloroplasts
  • The main structures of the mosses are ....
    Rhizoids, Cauloids, Phylloids, Reproductive structures ( sporangia, gametangia )
  • True or false. Gymnosperms have root, stem, leaves and flowers that produce fruits.
    False. Gymnosperms have root, stem, leaves and flowers that don´t produce fruits. Angiosperms form fruits.
  • True or false. Mosses are small plants with organs but no tissues. They have conducting vessels.
    False. Mosses are small plants with tissues but no organs. They don´t have conducting vessels.
  • True of False. Plants don't move at all
    False. They do move in response to various stimuli ( grow in direction of light, carnivorous plants shut their leaves )
  • Give two examples of asexual reproduction
    Spores and plant fragments
  • True or false. No type of plant forms tissues or have organs.
    False. They are tissue-forming organisms and most of them have organs including a root, a stem and leaves.
  • True or false. The leaves are the organs specialised in performing photosynthesis
    True
  • True or false. Gymnosperms, whose seeds are contained in a fruit. Angiosperms, whose seeds are not contained in a fruit.
    False. Gymnosperms, seeds are not in a fruit. Angiosperms, seeds in a fruit.
  • True or false. The abaxial surface is the upper side and the adaxial surface is the underside.
    False. Adaxial is upper side, abaxial is underside.
  • The main structures of the ferns are ...
    Roots, Stem or rhizome, Leaves of fronds, Reproductive structures ( sporangia-sori, gametangia )
  • Two types of sap circulate through the conductive vessels, what are they?
    Xylem sap ( mineral salts and water ), Phloem sap ( carbohydates and water )
  • Name two types of seedless plants
    Ferns and mosses
  • True or false. Monoecious, some plants have male flowers and other plants have female flowers.
    False. Monoecious, same plant has both male and female flowers.
  • The seedless plants alternate between sexual and asexual reproduction. Explain it.
    In same phases of their life they reproduce by gametes and in other phases by spores
  • True or false. The leaves have a flat part or blade, which is attached to the stem by the roots.
    False. The leaves are attached to the stem by the petiole or stalk.
  • True or false. Angiosperms flowers have no calyx or corolla.
    False. Gimnosperms flowers have no calyx or corolla.
  • True or false. The stem is the organ that keeps the plant upright and supports the part that´s underground.
    False. Supports the part that´s above ground.
