Most important plant family
|
grass family. 70 percent.
|
|
What are the main organs of flowering plants?
|
stems, roots, leaves, flowers.
|
|
What are the two most important things in science?
|
to observe and infer.
|
|
Vacuole
|
Recycling reservoir for some substances, and waste storage area for others; occupies most of the volume of a mature plant cell.
|
|
Dictyosome
|
Layers of flattened, membrane-bound sacs, functioning in secretion.
|
|
Nucleus
|
Large membrane-bound organelle containing the genetic material determining the cell's structure and function.
|
|
Mitochondrion
|
This organelle is much smaller in size than the chloroplast and releases energy.
|
|
Cell Wall
|
This part is a porous, nonliving, supportive, and protective shell of a plant cell.
|
|
Endoplasmic Reticulum
|
This part forms a continuous channel between the nucleus and plasma membrane.
|
|
Cytoplasm
|
Numerous membrane-bound, organized structures collectively called organelles are contained here.
|
|
Ribosome
|
Frequently found attached to the endoplasmic reticulum or scattered in the cytoplasm, functioning in the formation of protein.
|
|
Plasma membrane
|
Close to the cell wall, this very thin structure controls the movement of substances into and out of the cytoplasm.
|
|
Chloroplast
|
Numerous organelles containing green pigment responsible for the capture of light energy. Site of photosynthesis.
|
|
Prophase
|
The nuclear membrane and the nucleolus disappear in this phase, and the chromosomes first become visible during this phase.
|
|
Interphase
|
Chromosome duplication takes place during this phase.
|
|
Anaphase
|
During this phase the chromatids divide and move toward opposite poles.
|
|
Telophase
|
The nuclear membrane and nucleolus reappear in this phase.
|
|
Metaphase
|
All the pairs of chromatids gather at the equator during this phase.
|
|
What is the difference between cytoplasm and protoplasm?
|
The protoplasm does not have a nucleus.
|
|
When vinegar was added to the plant cell what happened?
|
The cytoplasm stopped moving.
|
|
What are the different types of leaf tissues?
|
Meristematic, ground, dermal, and vascular.
|
|
Meristematic
|
site of cell division. Without meristems, plants wouldn't grow.
|
|
Ground
|
constitutes most of the primary body of a plant. Functions: storage, metabolism, and support.
|
|
Dermal
|
forms the epidermis that covers the plant body.
|
|
Vascular
|
the plant's plumbing system, like long pipes that spread throughout a plant.
|
|
What are the different types of Leaf cells?
|
collenchyma, schlerenchyma, parenchyma
|
|
Collenchyma
|
long cells that support growing regions and are common in expanding leaves, petioles, and elongating stems.
|
|
Schlerenchyma
|
rigid cells that produce thick, nonstretchable, secondary cell walls. Support and strengthen non growing, non extending regions of plants such as mature stems.
|
|
Parenchyma
|
most abundant and versatile cells in plants. Identified by inconspicuous structure (not distinct).
|
|
Stomata
|
specialized structures in the epidermis. Abundant on the undersides of leaves. Allow CO2 to enter the leaf and fuel photosynthesis.
|
|
What are the phases of mitosis?
|
Interphase, Prophase, Metaphase, Anaphase, Telophase.
