In 1858, a scientist named ____ reasoned that existing cells had to arise from other preexisting cells. |
Virchow |
|
In plants, only certain types of cells called ____ cells are normally capable of dividing to form new cells. These cells are usually restricted to certain locations within the plant such as the tips of ____ and ____ |
meristematic roots shoots |

Cellular reproduction |
|
Lignified cell walls usually will be stained ____, whereas cell walls composed mainly of ____ will be stained with some shade of blue or green |
red cellulose |
|
These are found at the tip of roots and shoots which produce new cells to increase the length of the root or shoot |
Apical meristems |
|
These cells are a single superficial layer of cells covering all other primary tissues which are derived from the apical meristems |
Epidermal cells |
|
These cells protect the underlying tissues |
Epidermal cells |
|
Cells tend to have large vacuoles and may contain various secretions |
Parenchyma cells |
|
2 Clsssification of parenchyma cells |
Aerenchyma cells-have extensive connected air space Chlorenchyma cells-contain chloroplasts |
|
These are green pigments |
chloroplasts |
|
Elongated cells that provide excellent support and strengthening functions being located just beneath the epidermis and thickened at the corners |
Collenchyma cells |
|
Cells that support and protect due to the shape, thickness and toughness of their cell walls on which are deposited with lignin |
Sclerenchyma cells |
|
2 Classifications of Sclerenchyma cells |
Sclereids-isodiametric cells Fibers-elongated cells with pointed ends |
|
These are made up of vessel elements which are long tubes that are open at each end. Their walls are thickened forming a secondary wall that is deposited in different patterns |
Vessels |
|
5 types of vessels |
1. Reticulate vessels 2. Annular vessels 3. Spiral vessels 4. Pitted vessels 5. Sclariform vessels |
|
vessels wherein the lignin forms a network on the walls |
reticulate vessels |
|
in this type of vessel, the lignin deposits appear as separate rings |
annular vessels |
|
in this type of vessel, the lignin is laid down as spiral bands |
spiral vessels |
|
in pitted vessels, the walls are ____ |
pitted |
|
vessels that have the thickenings in the form of transverse, interconnecting bars |
Sclariform vessels |
|
these are tubes that are tapered at each end, with pits that allow passage of water between cells |
tracheids |
|
these are important for lateral short-distance conduction |
Rays |
|
These are flattened, thin-walled cells with little or no intercellular spaces |
Cork cells |
|
These cells make up the periderm that constitutes the outer bark of a woody stem |
Cork cells |
|
3 types of meristematic tissue |
1. Apical - for plant length 2. Lateral - for secondary growth and diameter 3. Intercalary - found at the basal portiom |
