Biology: Plants Flashcards
What are 4 features of a plant?
Embryo Formation, specialized water-conducting tissues, seeds and flowers
What are the 5 categories of a plant?
Flowering, Cone-Bearing, Ferns and Relative, Mosses and relatives and Green Algae
What are the 2 alternating plant phases?
Diploid phase and a haploid phase (shift between them is called alternation of generations)
What is the diploid phase and the haploid phase called? (Multicellular)
Sporophyte and gametophyte
What does a vascular plant have?
Tube-like structures that carry water through the plant.
What do non vascular plants have?
Water is absorbed through cells (NOT TUBE LIKE STRUCTURES)
What are vascular plants also known as?
Tracheophytes (due to water conducting cells, tracheid)
What is tracheid?
hollow tube like with thick cell walls
Where are tracheids found?
The Xylem
What is the Xylem?
A tissue that carries WATER UP from the roots to the rest of the plant
What is Phloem?
Transport nutrients and carbs (produced by photosynthesis) which goes UP and DOWN Phloem=Phood!
Algae…
Doesn’t make seeds; has no true roots or stems
Ferns…
Doesn’t make seeds, has leaves, roots and stems.
Mosses…
Don’t make seeds; have SOME roots, leaves and stems.
Monocots….
Have one cotyledon, fibrous roots, scattered vascular system, parallel veins on leafs, and flower petals are multiples of 3!
