Growth and Development in Plants — Flashcards

Answer

Growth in plants refers to an irreversible increase in the size, number, or volume of cells, tissues, or organs. It results from cell division, cell enlargement, and cell differentiation. For example,…

Answer

Development is the series of qualitative and quantitative changes a plant undergoes throughout its life cycle, including growth, differentiation, morphogenesis, and maturation. For instance, a seed de…

Answer

Growth is a quantitative change involving increase in size, number, or volume of cells. Development is a qualitative process involving differentiation, morphogenesis, and maturation. For example, a se…

Answer

The three stages are: (i) Cell Division – mitosis increases cell number; (ii) Cell Enlargement – cells expand due to increased protoplasm and water uptake; (iii) Cell Differentiation – cells specializ…

Answer

A sigmoid or S-shaped growth curve shows the pattern of plant growth over time. It has three phases: Lag Phase (slow initial growth), Log Phase (rapid growth), and Stationary Phase (growth slows and s…

Answer

1. Lag Phase: Initial slow growth as cells prepare for division. 2. Log Phase: Rapid growth due to high cell division and enlargement. 3. Stationary Phase: Growth rate declines and stabilizes as resou…

Answer

The grand period of growth is the total time during which a plant or organ grows at its fastest rate, typically corresponding to the log phase of the sigmoid curve. During this time, both cell divisio…

Answer

Plant growth in length is measured using direct methods like a scale or specialized tools like an auxanometer. For example, measuring the increase in stem length over a week using a ruler, or using an…
