3 Outline 1 Questions and answers 2 Plant cell Cellular transport Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
4 Questions and answers Previous final question: the answer What is the difference between chloroplasts and mitochondria? Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
5 Questions and answers Previous final question: the answer What is the difference between chloroplasts and mitochondria? While chloroplasts are synthesizing organic compounds, mitochondria produce most of cytoplasmic ATP (energy source) in the plant cell. The inner membrane of mitochondria form cristae Chloroplasts contain thylakoids bearing chlorophyll in their membrane Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
6 Plant cell Plant cell Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
7 Plasma mebmrane Plant cell Phospholipids, sterols, proteins: pumps, receptors, channels Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
8 Cell wall 1 Plant cell Root cells of an onion showing the cell wall (TEM 47, 000) Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
9 Cell wall 2 Plant cell Cellulose fibers in the plant cell wall (SEM) Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
10 Plant cell Primary and secondary cell walls Primary cell wall consists mostly of cellulose and proteins, they are thin and flexible Secondary cell wall includes hydrophobic lignine and suberine; this inclusion leads to the death of cell. However, dead cells are very useful for plants Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
11 Plant cell Secondary cell wall: molecules Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
12 Plasmodesmata 1 Plant cell Plasmodesmata in a corn leaf between a mesophyll cell and a bundle sheath cell (TEM) Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
13 Plasmodesmata 2 Plant cell E.R. = endoplasmic reticulum (endoplasmic network) Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
14 Plant cell Vacuoles, osmosis and turgor pressure If cell vacuoles contain more concentrated solution of salts then water surrounding cell (i.e., water outside is hypotonic), water will flow inside a cell. It is called osmosis Cell wall prevents cell from explosion due to high turgor pressure When water flows outside a cell, cell content will shrink: this is plasmolysis Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
15 Symplast and apoplast Plant cell Symplast name for continuous cytoplasm in set of cells Apoplast space outside cell; area of considerable metabolic activity Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
16 Plant cell Cellular transport Plant cell Cellular transport Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
17 Plant cell Cellular transport Endoplasmatic reticulum (network), ER Rough endoplasmic reticulum with ribosomes along outer surface. Manufactures many proteins destined for secretion or for incorporation into membranes (TEM) Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
18 Plant cell Cellular transport Goldgi apparatus (dictyosomes) 1 The Golgi is an organelle composed of stacks of flattened, membranous sacs mainly responsible for modifying, packaging, and sorting proteins that will be secreted or targeted to other organelles of the internal membrane system or to the plasma membrane Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
19 Plant cell Cellular transport Goldgi apparatus (dictyosomes) 2 Golgi complex and smooth endoplasmic reticulum in a liver cell (TEM) Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
20 Plant cell Final question (2 points) Cellular transport Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
21 Plant cell Final question (2 points) Cellular transport List at least two differences between plant and animal cells. Shipunov (MSU) Introduction to Botany. Lecture 10 September 23, / 20
22 Summary Plant cell Cellular transport Vacuole, chloroplasts and cell wall are three most important cell parts specific to plants. There are two ways of moving things between plant cells: through symplast or through apoplast ER handles ribosomes and packages proteins Golgi apparatus guides the movement of proteins Shipunov (MSU) Introduction to Botany.
