Do all plants have a seed coat?
Only seeds have seed coats not plants. Not all seeds have seed coats.
How do seeds with hard watertight seed coats able to germinate?
Seeds with hard, watertight seed coats can germinate by undergoing a process called scarification, where physical or environmental factors weaken or break down the seed coat, allowing water to penetrate. Additionally, some seeds require specific conditions such as temperature changes, fire, or passage through an animal's digestive system to initiate germination. Once the seed coat is breached and moisture is absorbed, metabolic processes begin, leading to germination. This adaptation allows seeds to survive harsh conditions until the right environment for growth is present.
What is an irregular cell that makes nutshells or seeds hard?
Sclereids are irregularly shaped cells found in nuts and seed coats. These cells are responsible for providing structural support and making the outer layer of nuts or seeds hard and resistant to mechanical damage.
The tough outer layer of a seed is called the?
the seed coat
How do plants look after their seeds?
Many seeds have hard coats or cases to protect them as they grow. Some plants also have tasty, colorful fruits glowing around their seeds. Animals eat the seeds along with the food. This helps to spread the seeds.
Do all plants have a seed coat?
Only seeds have seed coats not plants. Not all seeds have seed coats.
The gritty stone cells of pears the hard cells of seed coats and plant fibers are examples of?
These are examples of plant structures that provide protection for the seeds and help in seed dispersal. The gritty stone cells of pears and hard cells of seed coats act as barriers against physical damage, while plant fibers aid in the dispersal of seeds by wind or animals.

Why will a seed not grow into a tree?
If you have a seed that is a tree seed, then it will grow into a tree. The corn plant is not a tree seed, but the peach seed is. The acorn is a tree seed, the pine cone is a collection of pine seeds. Now you get the point.
Howdoe the ease of splitting open a monocotyledon seed compare with that of splitting open a dicotyledon seed?
Monocotyledon seeds have a single seed leaf, making them generally easier to split open compared to dicotyledon seeds, which have two seed leaves. The structure of monocot seeds is simpler, allowing for easier access to the embryo inside. Dicot seeds, on the other hand, tend to have harder seed coats that may require more effort to split open.
What are 3 mechanisms and adaptations for seed dispersal?
Three mechanisms for seed dispersal are wind dispersal (seeds carried by wind currents), animal dispersal (seeds carried by animals), and water dispersal (seeds carried by water currents). Adaptations for seed dispersal include structures like wings or hairs on seeds that aid in wind dispersal, fruit that attracts animals to eat and disperse seeds, and buoyant seed coats that enable water dispersal.
What is the difference between nuts and seeds?
Nuts are a type of seed, but not all seeds are nuts. Nuts are a specific type of seed that is enclosed in a hard shell, while seeds can refer to a wider variety of plant reproductive structures.
Why is it important to test a seeds before planting?
Soaking is a common practice on with some seeds to increase or speed up the rate of germination. Seeds with thick testa (seed coats) are generally better candidates. Soaking allows water to penetrate the seed coat a lot faster than if the seed was simply placed in damp soil.
How does seed protect itself from insect?
Some seeds have an outer covering which makes it hard for insects and animals to get into. Sunflower seeds have a hard outer shell to protect itself from predators.
Does scarification affect the rate of germination?
Scarification can actually have a positive effect on the rate of germination for certain seeds. By nicking, scratching, or softening the seed coat, scarification can help water and oxygen reach the embryo more easily, thus promoting germination. It can be especially helpful for seeds with hard or impermeable seed coats.
Why you have need to mix sand with seed before planting?
Well it makes the seeds nice and hard!
