The document discusses different types of sugars and their ability to act as reducing agents. It states that monosaccharides are reducing sugars because of their simple structure. The disaccharides maltose and lactose can also act as reducing agents because they have open chemical structures that allow them to be broken down. However, sucrose and polysaccharides are non-reducing sugars. Sucrose has a closed structure that bonds its rings together, while polysaccharides like starches have multiple bonded rings. Both of these structures prevent them from being easily broken down.
Plant cell
Robert Hooke discovered cells in 1665 using an early microscope. He observed the structures of cork cells. The development of electron microscopes in the 1930s allowed scientists to view cells and organelles at much higher magnifications. Key discoveries included the nucleus by Brown in 1831, living cells by Van Leeuwenhoek in 1674, and the proposal of the cell theory by Schleiden, Schwann, and Virchow from 1838-1858 stating that cells are the fundamental unit of life. Plant cells have additional structures like a cell wall and chloroplasts. The main components of plant cells are the cell membrane, cytoplasm, and nucleus.

Eukaryotic and prokaryotic cells differ in their nuclear structure and cell division processes. Eukaryotic cells have a membrane-bound nucleus containing chromosomes and a nucleolus, while prokaryotic cells lack a membrane-bound nucleus and nucleolus. Eukaryotic cells divide their nucleus through mitosis and may undergo meiosis, whereas prokaryotic cells usually divide their nucleoid through binary fission without mitosis or meiosis.
Structure of cell
Cells are the fundamental unit of life and come in two main types: prokaryotic and eukaryotic. All cells contain a nucleus that holds genetic material and organelles suspended in cytoplasm enclosed by a cell membrane. Cells perform essential functions like providing structure, transporting substances, producing energy, and reproducing through processes like mitosis and meiosis. The cell theory states that all living things are composed of cells, cells are the basic unit of life, and new cells are produced from existing cells.
Comparing plant and animal cell
Plant cells have a cell wall and chloroplasts that animal cells lack. Animal cells contain centrioles absent in plant cells. Both cell types share a nucleus, plasma membrane, cytoplasm, mitochondria, endoplasmic reticulum, Golgi body, vacuoles/vesicles, and lysosomes. Their shapes also differ, with plant cells typically being rigid and rectangular while animal cells are rounded and irregular.
Cellular Theory Introduction
The cell theory developed from early microscopic observations of cells by scientists like Robert Hooke, Anton van Leeuwenhoek, and Matthias Schleiden. The cell theory has three main principles: (1) all living things are made of one or more cells, (2) the cell is the basic unit of structure and organization of living things, and (3) all cells come from preexisting cells through cell division. There are two main types of cells - eukaryotic cells, which have a nucleus and membrane-bound organelles, and prokaryotic cells, which lack a nucleus and organelles.
The plant cell
The plant cell contains several organelles that carry out essential functions. It has a cell wall made of cellulose that provides structure and support. Inside the plasma membrane are organelles including the nucleus that contains DNA, mitochondria and chloroplasts that have their own DNA, the endoplasmic reticulum that transports materials, and vacuoles for storage. Ribosomes produce proteins, and the Golgi apparatus packages cell products. Together these organelles allow the plant cell to grow, carry out photosynthesis and respiration, and transport materials.
Different types of plant cells
Parenchyma, collenchyma, sclerenchyma, phloem, and xylem are the fundamental tissues in plants. Parenchyma cells perform photosynthesis and store products. Collenchyma and sclerenchyma provide structural support. Phloem transports food throughout the plant via sieve tubes and companion cells. Xylem transports water and minerals upwards via tracheids and vessels. These tissues work together to support and transport nutrients and water in plants.

Plant & animal cell for discussion
This document summarizes the key differences between plant and animal cells. It explains that both cell types contain organelles that maintain life processes like nutrient intake, movement, growth, response to stimuli, gas exchange, and waste removal. However, plant cells have additional structures like a cell wall, chloroplasts, and central vacuoles that are not present in animal cells. The chloroplasts allow plant cells to perform photosynthesis by capturing light energy.
Animal cell (project)
The document summarizes key components of animal cells:
- Animal cells contain organelles such as the cell membrane, nucleus, cytoplasm, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles. The cell membrane encloses the cell and is selectively permeable. The nucleus contains DNA and directs protein synthesis. Mitochondria generate ATP to power cellular processes.
- Animal cells differ from plant cells in lacking cell walls, chloroplasts, and having smaller vacuoles. Due to their lack of a cell wall, animal cells can adopt varied shapes while plant cells maintain a rectangular shape.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
