Is a Volvox a living thing?
Volvox are protists that live in colonies, or groups of organisms living together. They are both autotrophs and heterotrophs. They use their eyespot to detect light when they undergo photosynthesis. They also have tails, or flagella, they use to move the colony.
What kind of life cycle does Volvox have?
Volvox is haploid (n) algae, the haploid gametes fertilize to make diploid zygote (2n) which divides by meiosis to make haploid cells (n) which mature into haploid Volvox colony (Fig. 7, 8).
What is a Volvox organism?
Volvox, genus of some 20 species of freshwater green algae (division Chlorophyta) found worldwide. Volvox form spherical or oval hollow colonies that contain some 500 to 60,000 cells embedded in a gelatinous wall and that are often just visible with the naked eye.
Is Volvox prokaryotic or eukaryotic?
Volvox is a eukaryotic green algae. Algae of the genus Volvox are an example of the link between colonial organisms and multicellular organisms.
What supergroup is Fucus?
The intertidal seaweed genus Fucus (supergroup Heterokonta; Phaeophyta) is an ideal group in which to study speciation.
Is Volvox a phytoplankton or zooplankton?
Vibrio cholerae is responsible for a large number of waterborne outbreaks (Alam et al., 2006) and has been detected both in the planktonic state and also attached to both abiotic and biotic surfaces that have included zooplankton (e.g. amoebae), phytoplankton (e.g. Volvox) and cyanobacteria.
What is the life cycle of green algae?
There are four types of life cycle in algae such as Triphasic Life Cycle, Diplohaplontic Life Cycle, Diplontic Life Cycle, and Haplontic Life Cycle.
What is daughter colony?
daugh·ter col·o·ny. a secondary colony growing on the surface of an older colony; it is smaller and may have characteristics different from those of the mother colony.
What supergroup is paramecium in?

Is Cladophora Heterogametic?
Gametes are haploid in nature. When the male and female gamete cannot be differentiated morphologically, the gametes are known as homogametes or isogametes. For example, Cladophora (an algae). When male and female gamete can be differentiated morphologically, such gametes are known as heterogametes.
Is Daphnia a zooplankton?
D. magna is a relatively large zooplankton species which makes it so vulnerable to fish predation that it is excluded from fish-inhabiting lakes. It occurs mainly in ephemeral habitats like small ponds and rockpools where vertebrate predators are rare.
How is Volvox classified in the Chlorophyceae?
Volvox is classified in the class Chlorophyceae due to the presence of chlorophyll. Common species are Volvox aureus, Volvox globator, V. carteri, V. barberi, etc. Two equal-sized flagella are present in each cell anteriorly. The coordinated movement of flagella enables the colony to move in the water
What kind of life cycle does a volvox have?
Volvox Life Cycle 1 The life cycle of Volvox is haplontic, i.e. 2 Volvox show cell differentiation in terms of reproductive and somatic cells 3 Most of the species reproduce by both mechanism, asexual under the favourable condition and sexual reproduction during the unfavourable condition
What kind of structure does a volvox have?
Scientific Classification Domain Eukaryota Kingdom Plantae Phylum Chlorophyta Class Chlorophyceae Order Chlamydomonodales
What kind of habitat does a volvox live in?
Volvox are found throughout the world, inhabiting various temporary and permanent freshwater-bodies such as tanks, ponds, lakes, ditches, and puddles. They exist by forming colonies known as coenobium. They multiply fast in nutrient-rich environments, especially during the rainy season, often causing their habitat water-bodies to turn green.
