What is a cell wall?
|
A cell wall is a nonliving permeable wall that surrounds the plasma membrane and supports the cells of most plants.
|
|
|
What is plasmodesmata?
|
Minute strands of cytoplasm that extends through pores in the cell wall that enables chemical communication.
|
|
|
What are vacuoles?
|
Vacuoles occupy more than 99% of a cells volume and contains fluid with dissolving salts, sugars, or other substances.
|
|
|
What are chloroplasts?
|
The site of photosynthesis, the process by which light energy is converted into a form of energy that the plant can use to grow and reproduce.
|
|
|
What are the three main plant tissues called?
|
Parenchyma, collenchyma and sclerenchyma.
|
|
|
Describe parenchyma cells.
|
Parenchyma is the simplest tissue type. Parenchyma cells have thin cell walls and large central vacuoles.
|
|
|
Describe collenchyma cells.
|
Collenchyma cells have cell walls that are unevenly thick. they are used for support that needs to grow quickly.
|
|
|
Describe sclerenchyma cells.
|
Sclerenchyma cells have thick cell walls and secondary cell walls. It is found in stems, associated with leaf veins and in the outer covering of seeds and nuts .
|
|
|
What organelle generally stores pigments and energy?
|
Plastids.
|
|
|
What plastids contain pigments other than chlorophyll?
|
Chromoplasts.
|
|
|
What are carbohydrates usually stored as?
|
Starch
|
|
|
What does haploid mean?
|
Having one set of genetic material.
|
|
|
What does diploid mean?
|
Having two sets of genetic material.
|
|
|
In plant reproduction, fertilization does not happen without what?
|
Meiosis.
|
|
|
What does meiosis produce?
|
Meiosis produces two haploid cells by dividing a diploid cell.
|
|
|
What does fertilization produce?
|
Fertilization produces one diploid cell by fusing two haploid cells.
|
|
|
Describe sporophytes.
|
Sporophytes are generally multicellular, diploid, and produce haploid cells via meiosis.
|
|
|
Describe gametophytes.
|
Gametophytes are generally multicellular, haploid, and produce unicellular gametes (egg and sperm).
|
|
|
What is the cotyledon?
|
It is the plant tissue covering the seed. Think peanut plants and how it has 2 old leaves moving up the stem with the plant.
|
|
|
What Phylum are cellular slime molds from?
|
Dictyostilomycota
|
|
|
What Phylum are true slime molds from?
|
Myxomycota
|
|
|
What Phylum are water molds from?
|
Oomycota
|
|
|
What are mycologists?
|
Fungus experts
|
|
|
Is the dominant life stage of water molds diploid or haploid?
|
Diploid
