Roots Flashcards
What is the primary function of roots in plants?
Anchorage
Roots provide stability by anchoring the plant into the soil.
What is one of the key functions of roots related to water?
Absorption of Water and Nutrients
Roots take up water and essential nutrients from the soil.
What do roots store for future use?
Food and Nutrients
Roots can store carbohydrates and other nutrients.
What function do roots serve in the transport of substances?
Conduction
Roots conduct water and nutrients to other parts of the plant.
What are roots responsible for in terms of plant development?
Growth and Hormone Production
Roots produce hormones like auxins that regulate plant growth.
Auxin
hormone that is associated with root functions and is crucial for growth and development in plants.
Root cap
It protects the delicate root tips when it clears its path through the dirt
It protects the delicate root tips when jt clears its path through the dirt
Root cap
The region of cell division
Region of Meristematic activity
Apical Meristem cells (Region of Elongation)
These cells help in the growth of roots
Which region are root hairs found?
Region of Maturation
Root hairs are essential for the root _______.
Epidermis
Pith
Central core of parenchyma cells and is present in monocot
Pericycle
A thin layer of plant tissue found just inside the endodermis and surrounding the vascular cylinder.
Endodermis
Acts as selective barrier, regulating the movement of water, ions, and nutrients into the vascular system
Hypodermis (Cortex)
Located just beneath the outermost layer that provides additional support
Bundle sheath
In roots, this refers to the cells surrounding the vascular cylinder
What are the different types of root movements?
Positive geotropism, Positive hydrotropism, and Negative Phototropism
What are the different types of root movements?
Positive geotropism, Positive hydrotropism, and Negative Phototropism
Growth of roots towards gravity
Positive Geotropism
Growth towards the water
Positive Hydrotropism
Movements of roots away from sunlight
Negative Phototropism
Storage roots
These roots store extra foods and nutrients
Prop roots
These roots grow from the stem down into the soil, providing extra support for the plant.
Aerial roots
These roots grow above the ground and can absorb moisture from the air.
Buttress roots
These are large, wide roots at the base of trees, providing additional support
Pneumatophores
These are specialized roots that grow upwards, allowing plants in swampy areas to access oxygen.
Suckers
aboveground stem that developed from adventitious buds on the roots, for asexual reproduction
