How are bulliform cells different from adaxial epidermal cells? | Bulliform cells are large, empty and colourless. |
Bulliform cells develop from | Adaxial epidermal cells |
What difference is brought about in the vascular bundles in monocot and dicot leaves because of the veination? | Vascular bundles in a dicot leaf vary in size because of the varying size of veins in reticulate veination. Vascular bundles of a monocot leaf are almost similar in size (except midrib vascular bundles) because of similar sized veins in parallel veination. |
Which type of cambium is present in young dicot stems? | Intrafascicular cambium |
Which develops first-intrafascicular cambium or interfascicular cambium? | Intrafascicular cambium |
What develops into interfascicular cambium in stems? | Cells of medullary rays |
On which side is the cambium more active in stems? | Inner side |
Secondary medullary rays develop from | Cambium |
What type of cells are present in the phellogen? | Narrow, thin walled and rectangular cells |
What is also known as secondary cortex in plants? | Phelloderm |
What type of cells are present in secondary cortex? | Parenchymatous cells |
What forms lenticels? | Ruptured epidermal cells |
What does the root vascular cambium originate from? | Tissue located just below phloem tissue, a portion of tissue of pericycle, just above the protoxylem |
How are schizogenous cavities formed between cells? | By the separation of cell wall at point of contact |
How are lysogenous cavities formed between cells? | By dissolution of some cells |
How are schizolysogenous cavities formed between cells? | First start as schizogenous and later become lysogenous. |
Which are the most common type of intercellular cavities in plants? | Schizogenous cavities |
Dicot stems may bear trichomes and many stomata. True or false? | False. | Dicot stems may bear trichomes and few stomata. |
Which layer of dicot stem provides mechanical support to young stems? | Hypodermis (made of collenchyma ) |
