Describe which adaptations of a seed would enable it to germinate in a vacant lot where a building once stood?
Adaptations that would enable a seed to germinate in a vacant lot include a hard, protective seed coat that can withstand harsh conditions and prevent desiccation. Additionally, seeds with a dormancy mechanism can remain viable for extended periods until favorable conditions arise, such as adequate moisture and temperature. A high sensitivity to environmental cues, like light or temperature changes, can also trigger germination when the lot becomes suitable for growth. Finally, a seed's ability to store nutrients allows it to sustain initial growth in nutrient-poor soil conditions often found in vacant lots.
Why is science hard?
Science is not that hard just study and work hard! For me it comes really easy.
What is mop and glo?
Mop & Glo is a brand of cleaning products designed for maintaining and shining hard floors, such as tile, laminate, and hardwood. It typically comes in a liquid form that can be mixed with water for mopping or used as a no-rinse cleaner to enhance the shine of floors. The product is known for leaving a protective coating that helps to resist dirt and stains while providing a glossy finish.
What would you expect to find if you left the bread for six months?
If you left the bread for six months, you would likely find significant signs of mold growth, as bread provides an ideal environment for mold spores to thrive. Additionally, the bread would be hard and stale due to moisture loss and potential drying out. Depending on the storage conditions, you might also notice other forms of spoilage or a foul odor. Overall, the bread would be inedible and unsuitable for consumption.
What are the functions of a hard disk?
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
What are the disadvantages of reproducing using spores?
Advantages - Spores are covered by a hard protective coat which enables them to survive under unfavourable conditions like lack of water and extreme temperatures. But when the conditions are favourable, the spores grow to produce new plants. This help them to run their species at any type adverse condition or environment. Thus the advantage is that despite of unfavourable environment, their species will not be demolished.Disadvantages - spore formation process is quite primitive.
What do you call a cell with a hard protective coat around it?
spore
Hard protective cover of a seed?
Seed coat is the hard protective cover of a seed, acting as a barrier to prevent desiccation, damage, and potential threats. It plays a crucial role in seed dormancy and germination processes.
Which creatures are usually covered with scales?
Reptiles, such as snakes, lizards, and turtles, are typically covered in scales. Scales are hard, protective structures made of keratin that help these animals retain moisture and provide a barrier against predators.
How you can get mushroom seed?
ANSWER:Mushrooms don't have seeds, they have spores. You can get mushroom spores by tapping a mature mushroom and collecting the spores to transfer to another growth medium. They are very minute and hard to see.
Do a harvestman have a shell?
No, harvestmen, also known as daddy longlegs, do not have a shell. They have a small, oval body without a hard protective covering. Instead, their body is flexible and covered with a thin layer of skin.
Why are microbial spores resistant to dessication?
. They are so hard to kill because of their structure. They have a unique cellular structure. They have a hard outer coat surrounding the spore. This makes it hard for disinfectants to penetrate. There is a very thick layer beneath the coat call the cortex. This gives it resistance to heat. There is a germ cell wall under the cortex.Under the germ cell is the inner membrane and it is a permeability barrier against many potentially damaging chemicals.
Why does a seed have a better chance of growing into a new plant than a spore does?
Seeds are protected by a hard outer coat that helps them survive harsh conditions and provides nutrients for growth. Additionally, seeds contain an embryo that is ready to start growing once it receives the right conditions. Spores, on the other hand, are microscopic and lack protective structures, making them more vulnerable to environmental stresses.
Why are spores more difficult to stain than vegetative cells?
Spores are very hard and dense, dye is not readily absorbed into the endospore. However, one method of staining is the Schaeffer and Fulton method. The stain is malachite green and the proper method entails preparing a heat fixed smear which is covered by a piece of blotting paper, and flooded with the dye. Wait 15 mins then remove blotting paper and wash. Counterstain with 0.5% Safrinin. Spores appear green.
What are a grasshoppers body covered with?
Their body is covered with a hard exoskeleton.
What does seed coat protect?
Since the coat is hard it protects from being eat or like chewed
What is a seed coat on a lima bean?
The seed coat of a lima bean is the protective outer layer that encases the seed. It serves to shield the seed from physical damage, pathogens, and environmental factors while also helping to retain moisture. The seed coat is typically hard and may vary in color, providing a barrier until the conditions are right for germination. Once the seed absorbs water and swells, the seed coat splits, allowing the plant to emerge.
