What are the three stages of growth?
The three stages of growth: Initiate – Create – Scale. There are three main phases of growth: cell division, cell enlargement, and cell differentiation. Growth curves include the absolute growth curve, absolute growth rate curve, and relative growth rate curve.The classic growth curve, as exemplified by a newly established bacterial colony, is divided into four phases, in order of their appearance: (1) lag phase; (2) log (logarithmic), or exponential, phase; (3) stationary phase; and (4) death, or decline, phase.
What is the first stage of growth in plants?
Germination and Sprout The seed imbibes (takes in) water, causing it to swell and exert pressure that cracks its protective outer shell. The radicle (tiny root) is the first part to emerge, anchoring the plant in the soil. This is followed by the plumule (shoot), which will develop into the stem and leaves. The seed gets air, water, and warmth. The seed soaks up water; seed coat breaks and the root emerges. The new plant develops roots and a shoot. As the plant grows in size, it develops leaves.Summary of Life Cycle of a Plant Life Cycle of a Plant is defined as the journey of a plant from a seed to a mature plant and back to producing seeds again. Stages: Seed Germination Seedling Mature Plant Flowering Fruit Death.In hypogeal germination the epicotyl extends and the cotyledons stay in the ground, whereas in epigeal germination the hypocotyl extends and the cotyledons come out of the ground.Germination is the process of seeds developing into new plants. First, environmental conditions must trigger the seed to grow. Usually, this is determined by how deep the seed is planted, water availability, and temperature.Germination is the fundamental process in which the sown plant seeds are grown into young plants or seedlings. Based on their growing conditions and the fate of the cotyledons, the process of germination is classified into two main types: Epigeal Germination. Hypogeal Germination.
What are the three stages?
The law of three stages is an idea developed by Auguste Comte in his work The Course in Positive Philosophy. It states that society as a whole, and each particular science, develops through three mentally conceived stages: (1) the theological stage, (2) the metaphysical stage, and (3) the positive stage. Comte attempts to elucidate that social change occurs in three stages: the Theological Stage (fictional), the Metaphysical Stage (abstract), and the Positive Stage (scientific). These three stages are considered universal laws that generalize the evolution of society throughout its history.
What are the primary 3 life cycles of plants?
The three main stages in the life cycle of a flowering plant are: seed, young plant and adult plant. The seed is generally found in the fruit of a plant. The diagram below shows a cross-section of a seed. There are the 5 stages of plant life cycle. The seed, germination, growth, reproduction, pollination, and seed spreading stages.Background: The plant life cycle consists of four stages; seed, sprout, small plant, and adult plant. When the seed gets planted into the soil with water and sun, then it will start to grow into a small sprout.Plants’ lives may be as short as a few weeks or months, but they go through distinct changes as they grow, just as people do. The stages that plants go through are from seed to sprout, then through vegetative, budding, flowering, and ripening stages.Plants’ lives may be as short as a few weeks or months, but they go through distinct changes as they grow, just as people do.

What is the 3rd stage of plant growth?
Stage 3: Stem Elongation Or Rosette Growth And Shoot Development. Some parts of the plant, like stems and roots, keep growing throughout the plant’s life: this process is called indeterminate growth. New cells are produced at the tips of growing shoots. There are three phases of growth – meristematic, elongation and maturation. We can understand this better by looking at a seed. We already know that the tips of roots and shoots exhibit continuous growth and hence are meristematic.The third phase is the growth phase, when the radicle emerges from the seed and begins to develop into the root (Figure 1). As the root develops, it anchors the plant and begins to absorb water and nutrients from the surrounding substrate (soil or planting mix).
