Biology labs: Plants Flashcards
What does a compound leaf look like and what are the two versions?
Multiple leaves attached to a long stem attached to the main stem. Can be palmately compound (leaves in a star formation attached to a stem) or pinnately compound (normal)
What dos a simple leaf look like?
One leaf attached directly to a stem
What does a pinnate leaf look like?
One main vein with others branching off
What does a palmate leaf look like?
Many veins branching from base of leaf
Where is the petal and what does it do?
Outer section, attracts pollinators, may be brightly colored
Where is the stamen and what does it do?
Male reproductive part of flower, has anther and filament
Where is the anther and what does it do?
Top part of stamen, contains pollen
Where is the filament and what does it do?
Lower section of stamen, holds up anther
Where is the pistil and what does it do?
Female reproductive part of flower, has stigma, style and ovary
Where is the sigma and what does it do?
Part of pistil, receives pollen during fertilization, is sticky
Where is the style and what does it do?
Part of pistil, tube to sigma
Where is the ovary and what does it do?
Part of pistil, contains ovules that will form into seeds
Where is the septal and what does it do?
Small leaves under the flower, first leaves for baby plant
What is another word for stem?
Peduncle
What do you call all of the sepals?
Calyx
What does Xylem do?
Carries water
What does Phoem do?
Carries food
What is dermal tissue?
Tissue that forms the protective layer of a plant, forms skin called epidermis
What is vascular tissue and what are the two types?
Tissue that transports water and food to and from different parts of the plant, Xylem and Pholem
What is ground tissue?
Makes up the insides of fleshy parts of a plant, like roots, stems and leaves
What is the terminal bud?
The bud at the tip of a stem
What are the lateral buds?
The buds that form between the leaf stalk and the stem
What are the bud scales?
Structures that protect the tissues within the bud
What are bud scale scars?
Scars leaf behind when the bud scales fall off and the bud begins to grow
What are leaf scars?
Scars left behind when the leaves that fall from the stem in autumn. They are directly below the lateral bud.
What are lenticels?
Raised areas (that look like pores or holes) that allow gases to be exchanged between the inner tissues of the stem and the surrounding air
What is a way to age a stem without cutting it down?
Counting the bud scale scars
What is sapwood?
Xylem that still conducts water (outside layer)
What is heartwood?
Xylem that does not conduct water (inner layer) and is much darker
What is springwood?
Large xylem cells produced in the spring that are light colored and wide
What is summerwood?
Small xylem cells produced in the summer that are dark colored and thin
Where is the phloem in a tree?
A small area that lies outside of the xylem
What does bark do? (2)
Protect the tree from damage and prevents water loss
