All plants share the following characteristics :
Eukaryotic plant cells; multicellular; autothophic organisms; reproduce sexually or asexually; live attached to a substrate.
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 root is the organ that attaches the plant to the ground and absorb water and mineral salts
True
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.
True or false. The leaves are the organs specialised in performing photosynthesis
True
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. The abaxial surface is the upper side and the adaxial surface is the underside.
False. Adaxial is upper side, abaxial is underside.
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. 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.
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. 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.
The main structures of the mosses are ....
Rhizoids, Cauloids, Phylloids, Reproductive structures ( sporangia, gametangia )
