Are alternation of generations haploid and diploid all types of sexual life cycles?
True ...
What algae shows a distinct alternation of generations?
The green alga Chlamydomonas exhibits a distinct alternation of generations, alternating between haploid and diploid stages. In its life cycle, the haploid gametophyte produces gametes through mitosis, which fuse to form a diploid zygote. The zygote then undergoes meiosis to produce haploid spores, completing the cycle. This alternation between the haploid and diploid phases is a key feature in the life cycles of many algae.
What are some similarity between haploid and diploid?
Haploid and diploid cells both contain genetic material in the form of DNA, which carries the instructions for an organism's development and function. Both types of cells can undergo processes such as replication and transcription, allowing them to produce proteins essential for cellular functions. Additionally, both haploid and diploid cells play crucial roles in the life cycles of organisms, contributing to reproduction and genetic diversity.
Which of the life cycles is typical for most fungi and some protists?
The typical life cycle for most fungi and some protists is the haploid-dominant life cycle. This means that the predominant stage in their life cycle is haploid, with the fusion of haploid cells (usually through sexual reproduction) forming a diploid zygote that undergoes meiosis to produce haploid spores.
Where in the human body are haploid cells found?
Haploid cells are also known as reproductive cells. These cells only contain one-half of the required chromosomes for a new baby to be created (the other set of chromosomes are in diploid cells). Haploid can be found in testicles and ovaries in humans, but are also found in algae's and bacteria's.

What do all plant life cycles have in common?
All plant life cycles involve alternating generations between a haploid (gametophyte) and a diploid (sporophyte) phase. This alternation allows for sexual reproduction, with gametes produced by the gametophyte combining to form a new diploid sporophyte generation.

What are haploid cells?
it is sperm. NEW ANSWER Ploidy refers to how many complete sets of chromosomes a cell has. A diploid cell will have two sets of chromosomes, one set from each parent. A haploid cell is a cell with only one set of chromosomes. For example, humans are diploid organisms - our cells each have two copies of 23 different chromosomes for a total of 46. Humans do produce haploid sperm and egg cells (with only one set of chromosomes for a total of 23 chromosomes per cell) during meiosis for reproduction as these two haploid cells can then fuse to produce a diploid fertilized embryo. However, not all haploid cells are sex cells for multicellular organisms. All prokaryotes (i.e. bacteria) are considered haploid because they have a single circular chromosome. Many organisms - plants, funghi, yeast - go through haploid and diploid stages of their life cycles. Some insects are haploid.

Which of the following occurs in meiosis but not mitosis?
Meiosis is the division of the gametes(sex cells), haploid (n) Mitosis is cell division, diploid (2n) In meiosis, there are the similar cycles (prophase, metaphase, anaphase, and telophase), but there are two cycles of each (ex: prophase 1, prophase 2 ETC).
Which cells would you expect to be haploid?
Firstly, a haploid cell is a cell that contains one set of chromosomes (n). Some examples include gametes (sperm and egg) and prokaryotes. Also, plants have haploid stages in their alternation of generations (or life cycles). This stage is called the gametophyte.
What is a diplontic life cycle?
in this diplontic life cycle the diploid sporophyte is the dominant photosynthetic independent phase of plant body.the haploid phase is represented by gametes only.this kind of life cycle is termed as diplontic life cycle.
