Plant Cell-Organelles
Organelle responsible for cellular respiration, often called the powerhouse of the cell.
What is the mitochondrion (mitochondria)?
What is the main composition of the plant cell membrane?
What is the main composition of the plant cell membrane?
What is the main function of root hairs, and from which tissue layer do they extend?
They increase the surface area of the root for absorption and are extensions of single epidermal cells (dermal tissue).
The name of the lateral meristem that produces secondary xylem inward and secondary phloem outward.
What is the vascular cambium?
How do the guard cell shapes differ between grasses (like maize) and non-grass plants (eudicots)?
Grasses have dumbbell-shaped guard cells while most other plants have kidney-shaped guard cells.
I am a large membrane-bound compartment filled with cell sap that exerts pressure to drive cell expansion and stores secondary metabolites.
What is the vacuole (and its membrane, called the tonoplast)
Root tissue located between the cortex (parenchyma) and the pericycle.
Where is the endodermis?
Central part of the stem beyond the cortex.
Aside from the cell wall and chloroplasts, these organelles are only present in animal cells.
What are the lysosomes?
What are the centrioles? -centrosome
Aside from phospholipids, what other molecules are found in a cell membrane?
Proteins
Carbohydrates
The seed coat, nutrient source, and the _______ constitute the main parts of a seed.
What is the embryo?
Technically speaking in tree anatomy, I comprise all tissue layers outside the vascular cambium, including secondary phloem and periderm.
What is bark?
Equivalent to veins and arteries in the conducting systems of humans?
What is the xylem and phloem?
The microtubles and microfilaments contsitute a tube called the _____________, whcih participate sin mitosis.
What is the cytoskeleton?
Suberin layer located in one of the root tissues after the cortex that forces everythign to go simplastically
What is the Casparian strip?
Name of the specialized anatomical structure in C4 monocot leaves where large bundle sheath cells encircle the vascular bundles, separating initial carbon fixation from the Calvin cycle?
What is Kranz anatomy?
Connect cytoplasms of neigboring cells
What are plasmodesmata?
The narrow membrane-lined channels (40–50 nm in diameter) traversing cell walls that allow direct intercellular movement of proteins and nucleic acids between adjacent protoplasts.
What are plasmodesmata?
Which zone... at the root tip contains the protoderm, procambium, and ground meristem actively dividing right behind the root cap?
The region of cell division (or apical meristem).
Which three distinct tissue layers make up the periderm (the protective outer tissue that replaces the epidermis during secondary growth)?
1. Phellem (cork)
2. Phellogen (cork cambium)
3. Phelloderm
Region in which cells continue divide and differentiate
What is a meristem?
