Why can't a sperm without an acrosome fertilise an egg?
Gametes (Sex Cells) have adaptions to increase the chances of fertilization and successful development of an embryo. Sperm cells are produced in large numbers to increase the chance of fertilization. They have:-A tail to move them towards the egg cell-Many mitochondria to provide energy to make the approximate 12cm journey to the egg-An acrosome (tip of the head) that releases enzymes to digest and penetrate the egg membrane
What does the acrosome at the tip of the sperm head do?
The acrosome contains digestive enzymes that help the sperm penetrate the protective layer around the egg during fertilization. It plays a crucial role in allowing the sperm to fuse with the egg for fertilization to occur.
What cells are in an onion tip but not the onion?
The cells in an onion tip but not the onion itself are usually actively dividing cells located at the growing tip of the onion root, known as the root cap cells. These cells help protect the delicate meristematic cells responsible for root growth and can often be found in the root zone of plants.
What is special about a sperm cell?
Stem cells are basic cells. They are completely undefined and can become anything. Stem cells can be used the grow various organs due to this. The cells however would only be useful to the person that donated them. I hope this helps better than the previous nonsense answer
Is has special chemicals on the tip of its head to help it into things?
Yes, some animals have specialized chemicals or structures on the tips of their heads that aid in various functions, such as hunting or foraging. For instance, certain species of octopuses have cells that can release ink or other substances to distract predators or lure prey. Similarly, some insects have pheromones or other chemical secretions on their heads that help them communicate or attract mates. These adaptations enhance their ability to interact with their environment effectively.

What is the head of the match called?
...the head of the match a called the 'HEAD' or 'TIP'

Cells produced by the root and shoot tip meristems become the?
meristematic cells
Why are egg and sperm cells haploid?
Egg and sperm cells are haploid because they each contain half the number of chromosomes as a somatic cell (2n). This haploid state allows for the fusion of two haploid gametes during fertilization to restore the diploid chromosome number in the zygote. This ensures genetic diversity in offspring and maintains the correct number of chromosomes in species.
What differences are between the onion root tip and whitefish embryo in size of the cells?
The cells in the onion root tip are typically smaller and more uniform in size compared to the cells in a whitefish embryo. Additionally, the onion root tip cells are actively dividing, while the whitefish embryo cells are undergoing differentiation and organ development.

Why do your hens lay eggs with a dark brown crust at the tip of the egg?
the egg comes from the came orifice they use for their pooper.
What is the functional and structural regions of a sperm?
The functional regions of a sperm are the head, which contains genetic material, and the tail, which propels the sperm. The structural regions include the acrosome at the tip of the head, which contains enzymes for penetrating the egg, and the midpiece, which contains mitochondria for providing energy to the tail.
Does meiosis take place in root tip cells?
No. Meosis is a reductional division that brings about the generation of gametes. Mitosis takes place in the root tip cells. The root tip of a healthy plant is growing rapidly and there is a requirement for many newly formed cells.
