Name and describe the function of the five plant hormone groups discussed in your text. 5. Describe sexual and asexual reproduction in flowering plants. Be specific in regards to flowering plants. 1) Monocots are shorts for “Monocotyledons” which means plants whose embryo has one cotyledon; whereas, Eudicots (Eudicotyledons) carry embryo with 2 cotyledons.
The diploid state in plants is known as sporophyte which produces spores and the haploid state in plants is known as gametophyte which produces gametes. Unlike woman who always produce an egg and men who always produce sperm some plants have different dominate diploid stage than haploid stages. Some examples of plants with dominate haploid stages are green algae, mosses, liverworts and hornworts. Some examples of plants with dominate diploid stages are wiskferns, horsetails, and true ferns. ten ways in which plants in general or specific plants provide for you in your life and HOW they benefit or enrich your life 1.
A male sporangium 91) What is a stigma in a plant? The female part of the carpal that receives the pollen. 92) What part of the plant is the protective chamber where the eggs develop? 93) Pollen grains develop in the _____ and are trapped by the ______. Anther and stigma 94) What are the green leaves that enclose the flower before the flower opens?
Each stamen generally has a stalk called the filament (from Latin filum, meaning "thread"), and, on top of the filament, an anther (from Ancient Greek anthera, feminine of antheros "flowery," from anthos "flower"), and pollen sacs, called microsporangia. The development of the microsporangia and the contained haploid gametophytes, (called pollen grains) is closely comparable with that of the microsporangia in gymnosperms or heterosporous ferns. The pollen is set free by the opening (dehiscence) of the anther, generally by means of longitudinal slits, but sometimes by pores, as in the heath family (Ericaceae), or by valves, as in the barberry family (Berberidaceae). It is then dropped, or carried by some external agent — wind, water or some member of the animal kingdom — onto the receptive surface of the carpel of the same or another flower, which is thus pollinated. It is the part that contains the sperm
a) Plants produce O2 and sugars from CO2 b) Animals produce CO2 and H2O from sugars and O2 c) Plants produce O2 and sugars and animals produce CO2 and H2O d) Animals produce O2 and sugars and plants produce CO2 and H2 27. Think of the cell as a factory, in which the organelles are specialized sites of production. All cells have a power plant, the mitochondrion. Plant cells have an additional “reactor” for the production of usable energy. It is called the
GENETICS-1 1) Complex organisms produce sex cells that unite during fertilization, forming a single cell known as a) an embryo c) a gonad b) a gamete d) a zygote 2) A cell with a diploid chromosome number of 12 divided two times, producing four cells with six chromosomes each. The process that produced these four cells was most likely a) internal fertilization b) external fertilization c) mitotic cell division d) meiotic cell division 3) Which diagram represents a pair of homologous chromosomes? 4) In minks, the gene for brown fur (B) is dominant over the gene for silver fur (b). Which set of genotypes represents a cross that could produce offspring with silver fur from parents that both have brown fur? a) Bb x Bb c) BB x BB b) BB x bb d) Bb x bb 5) When a certain pure strain of fruit fly is cultured at a temperature of 16˚C, all of the flies will develop straight wings.
Spiracles are found behind each eye on most species. Chondrichthyes show three types of reproduction. Oviparous, this is defined as a method of animal reproduction in which eggs are laid by the female and develop outside the body. It is the most familiar form of reproduction. Ovoviviparous, is a zoological term that refers to animals that produce eggs but retain them inside the female body until hatching occurs, so that "live" offspring are born.
Sometimes there may be a little berry at the top of it depending on the season. It’s commonly known as goldenseal or yellow root. The goldenseal is binomial name is the Hydrastis Canadensis L. It comes from the Ranunculaceae or the buttercup family .Goldenseal plant comes from H. Canadensis species. The order of the goldenseal is the Ranunculales. It falls under the Plantae or plant kingdom, the subkingdom of the goldenseal is the Tracheobionta meaning vascular plants, and under the subdivision of spermatophyte which are seed plants.
By: Paige Meinke Photosynthetic pigments are pigments that reflect and absorb different ranges of visible light. The reflection of light gives the pigments their color. Photosynthetic pigments are found in autotrophs, which are organisms that use light energy to make their own food in a process called photosynthesis. Some examples of autotrophs are plants, algae, and cyanobacteria [ (Speer) ]. There are many different photosynthetic pigments in each of these that play a part in photosynthesis, but the most common pigments are chlorophyll “a” & “b”, phycocyanin, phycoerythrin and the carotenoids.
Giardia exists in active (trophozoite) and dormant (cyst) stages. Its active, motile , but noninfective, trophozoite stage takes place after the Giardia cyst has entered the host. Each cyst undergoes a process called excystation, by which it produces 2 to 4 trophozoites. The trophozoite has a length from 9 to 21 μm and width of 5 to 15 μm. Each trophozoite possesses two nuclei and four pairs of flagella.
