What structural adaptations evolved in land plants to allow them to cop with these environmental challenges?
Land plants evolved several structural adaptations to cope with environmental challenges such as desiccation, gravity, and variable light conditions. To prevent water loss, they developed a waxy cuticle on their surfaces and stomata for gas exchange. Their vascular tissues, xylem and phloem, enabled efficient water and nutrient transport, supporting upright growth and maximizing light capture. Additionally, roots anchored plants in soil, allowing them to access water and nutrients more effectively.
What holds plants tightly to the earth?
The roots of a plant hold it firmly in the ground.
In which direction do plants roots grow?
Plant roots typically grow in the direction of gravity, a process known as gravitropism. This helps roots anchor the plant in the soil and seek out nutrients and water for growth and survival. Additionally, roots may also respond to other environmental cues such as moisture and light.
How do roots help plants meet their needs?
Roots help plants absorb water and nutrients from the soil, providing essential resources for growth and development. They also anchor plants in the ground, providing stability and support against wind and other environmental factors. Additionally, some roots store food and water for times of scarcity, helping plants survive in challenging conditions.
What kind of roots does roots have?
Roots don't have roots, plants have roots.
What would happen to plants nutrition if plants did not have roots?
what would happen to plants nutrition if plants did not have roots
How can the plants like cactus and acacia live in desert with scarce water?
The plants are designed (or evolved) to store extra water in the plant body or in underground roots when there is rain or water available and the skin of the plants keeps moisture in the plant from evaporating.

Why are The roots of plants are important to photosynthesis?
Water used in photosynthesis by plants is made available by roots. That is why roots of plants are important to photosynthesis in terrestrial plants. Aqatic plants absorb water from their free surface, hence role of roots in these plants is limited.
What organs did the earliest plants have?
The earliest plants, known as bryophytes, had simple structures with no distinct organs like leaves, stems, or roots. They had a structure called a thallus which served as a basic form of a plant body to absorb nutrients and water. Over time, as plants evolved, they developed more complex structures with specialized organs.
Which plants have fine roots?
The plants that have fine roots : Kangkong etc.....
Do plants grow from roots?
Not all plants have roots (eg phytoplankton) and while some plants do grow form their roots (eg grasses), most plants do not grow from their roots but from their apical growing tip.
