Major Plant Groups
_________ are the land plants.
What are Embryophytes?
This type of vascular tissue is responsible for moving water within plants.
What is xylem tissue?
______ tissue makes up the outermost layer of a plant.
What is dermal tissue?
The underside of a leaf.
What is the abaxial side?
Unicellular, haploid, produced by mitosis.
What are gametes?
This group contains both the seedless and seed-producing vascular plants.
What are Tracheophytes?
This kind of tissue carries out photosynthesis, stores photosynthetic products, and helps to support the plant.
What is ground tissue?
_________ are plant cells that provide support for growing parts of young plants and herbaceous plants.
What are collenchyma cells?
This type of growth takes place in all types of plants, and is growth in length.
What is primary growth?
Multicellular, diploid, produced via fertilization.
What is the sporophyte?
This group has leaves called microphylls, which are small and have one single unbranched vein.
What are Lycophytes?
These cells are involved in photosynthesis and the storage of secondary compounds.
What are parenchyma cells?
________ tissue is a type of vascular tissue that moves nutrients within plants.
What is phloem tissue?
These take up nutrients and water from the soil and pass them into the vascular system.
What are root hairs?
Unicellular, haploid, produced by meiosis.
What are spores?
This group exhibits all of the following: seeds, flowers, and fruit.
What are Angiosperms?
The stalk that joins a leaf to the stem.
What is a petiole?
These type of plants cells make up the majority of vascular tissue, and provide support for woody plants.
What are sclerenchyma cells?
In this type of herbaceous stem, the vascular bundles are arranged in a ring.
What are dicot stems?
Multicellular, haploid, produced by mitosis.
What is the gametophyte?
This group exhibits both chlorophyll a and chlorophyll b.
What are Viridophytes?
These are regions of growth from totipotent cells.
What are meristems?
This is a type of meristem that results in secondary growth (which occurs only in woody plants).
What is the vascular cambium?
This regulates what compounds pass into the xylem.
What is the endodermis?
Special Question (X2 points!):
Describe, in words, the complete plant lifecycle. You may start at whichever stage you like.
A diploid, multicellular sporophyte produces unicellular, haploid spores via meiosis. The spores undergo mitosis to produce the haploid, multicellular gametophyte which then produces haploid, unicellular gametes via mitosis. The gametes fuse (fertilization) to form a zygote, which develops into the sporophyte.
