Question
1. The root system the plant in the soil and absorbs and leaves and at a from the soil, especially by means ofStems support the water and minerals from roots to the leaves. A leaf and a lateral bud occur The leaves carry on which requires (list the three requirements) 2. Place a check in froat of the correct descriptions of leaves: aspines of a cactus b.tendrils of a cucumber trap of a Vesus's flytrap 3. Label each type of root shown and describe its special function: 4. Complete the following table to indicate the differences between monocot and eudicot plants Plant Part Monocot Eudicot Leaf veins Vascular bundles in stem Cotyledons in seed Vascular tissue in rootExplanation / Answer
1. The root system fixes the plant in the soil and absorbs water and minerals from the soil, especially by means of osmosis. Stem supports the leaves and transports water and minerals from roots to the leaves. A leaf and a lateral bud occur at a node. The leaves carry on photosynthesis, which requires water, sunlight and carbondioxide.
2. a. Spines are modified leaves of cactus which help prevent loss of water through transpiration.
b.Tendrils of cucumber are specialized stem which is threadlike and used for support and attachment.
c. The trap of a venus flytrap is the true leaf.
3. a. Fibrous root system - all roots about the same size
b. Tap root system (modified for storage) - main root larger and grows faster than branch roots
c. Prop root - modified roots that arise from stem to provide extra support
4. Monocot Plant
Leaf veins - parallel veins
Vascular bundles in stem - scattered
Cotyledons in seed - one cotyledon
Vascular tissue in root - vascular tissue consists of alternating strands of xylem and phloem(radial arrangement)
Eudicot
Leaf veins - Reticulate veins
Vascular bundles in stem - arranged in ring
Cotyledons in seed - two cotyledons
Vascular tissue in root - Radial arrangement: xylem and phloem bundles area arranged alternatively in different radii
