LIFE-CYCLES of the GREEN PLANTS. Algae, Moss, Selaginella, Fern, Gymnosperm, Angiosperm. Green Algae life cycle: The haploid generation (on the left) produces gametes by mitosis. These fuse to form zygotes that develop into the diploid generation (on the right). The cells of the diploid generation produce spores by

We will NOT focus on gametic life cycles as these are primarily for animals (Bio 1B with John!). We'll look at Fungus (zygotic life cycle), Algae, Moss, Fern, Flowering Plant (including asexual) (sporic life cycles). 1. First some basics: Fertilization, Mitosis and Meiosis. Fertilization (syngamy) is the fusion of two haploid gametes
The perpetuation of these algae passes through a cycle of events involving more than one phase for a species and every phase must be able to survive or reproduce for the species to persist. In its life cycle, an alga usually cycles through different ploidy stages and this cycle is characterized by the occurrence of sporophyte
An algal bloom is an increase in the number of algal cells such that there is a reduction in water quality. Some species (about 50 of the 1,500 species) of blue-green algae can LIFE CYCLE BIOLOGY: Cyanobacteria can fix gaseous nitrogen, and are efficient at . www.spea.indiana.edu/clp/FinalCylindro%20Web.pdf.
The gametes by union form zygote, which on germination produces the sporophytic plant again. The sexually reproducing members of algae show various patterns of life cycles. It can be distinguished into the following four types : 1. Haplontic life cycle. 2. Diplontic life cycle. 3. Diplohaplontic life cycle. I) Isomorphic typei. ii
Cultivation involving a reproductive cycle, with alternation of generations, is necessary for many seaweeds; for these, new plants cannot be grown by taking cuttings from mature ones. This is typical for many of the brown seaweeds, and. Laminaria species are a good example; their life cycle involves alternation between a.
1. Plant Life Cycles & Algae. Alternation of Generations. Alternation of Generations. • Unlike animals, who have a direct life cycle, plants have two life stages. – Sporophyte & Gametophyte. • One is haploid (gametophyte). • One is diploid (sporophyte). • Plants alternate between these generations. • Each a distinct plant.
Sex = Introduction of some of the genes from one organism into another (prokaryotes) or the combining of all of the genes from two different parts (gametes) of the life cycle of an organism (eukaryotes).
